Many friends who come to the clinic often ask me one question: the scalp feels dry and tight, and may even develop fine cracks, yet applying moisturizer brings no relief — what is going on? I say that problems on the crown of the head often do not lie in the scalp itself, but in whether that "breath" above the body has the strength to rise. The crown of the head is the meeting place of all yang, and when yang qi is insufficient and clear yang fails to rise, the scalp is like land deprived of water — it is the first to crack and show you.
I. Worsening After Fatigue: The Body Is Saying "There Is Not Enough Qi"
In the Suwen · Ju Tong Lun, there is a very blunt statement: "Exertion consumes qi." These five words already explain this small matter thoroughly — fatigue is not merely "being tired"; what it consumes is the most fundamental driving force of the human body. When qi is insufficient, the first to lose nourishment is the crown of the head, the highest point of the body. Therefore this kind of dry, cracked scalp has a very distinct pattern: it eases somewhat after resting for two days on the weekend, and clearly worsens after continuous overtime, staying up late, and overwork, sometimes accompanied by scalp tightness, dry and brittle hair, and mental fatigue with lack of strength. Analyzed from the pathogenesis of Chinese medicine, this is a deficiency pattern, not a fire pattern.
Why is it that when exertion consumes qi, symptoms appear first precisely at the crown of the head? The head is the "meeting place of all yang"; the six yang meridians of the hands and feet all run upward to the head and face, while the Governor Vessel governs the yang of the whole body and runs straight up along the spine to the crown of the head. Yang qi is the "engine" within the human body, possessing the functions of propulsion, warming, and containment. When overwork damages yang qi, there is insufficient qi and blood rising to the head and face; the skin loses warming and nourishment, and dryness and cracking become unavoidable. At this point, if one mistakes it for "internal heat" and takes cold, cooling, purgative substances, the result is instead counterproductive.
Here a key direction must be distinguished: whether qi deficiency predominates, or yin-blood depletion predominates. The two directions differ — the former is "insufficient lifting power," while the latter is "insufficient material." Those with qi deficiency, besides dryness and cracking on the crown, often have fatigue, shortness of breath, easy sweating, and teeth-marked edges on the tongue; those with insufficient yin-blood more often have dry mouth and throat, unrefreshing sleep, and a sallow complexion. In clinical practice, many people also fall into a mixed state of both, requiring simultaneous care of both qi and blood, without stubbornly clinging to one side.
From the perspective of disease progression, this kind of deficiency damage mostly manifests as a process of slow accumulation and gradual worsening — it is not the cold of a single day. At the beginning there may only be occasional dryness, which slowly develops into persistent cracking. The disease location is in the scalp and skin, while the root involves the spleen and stomach — the spleen and stomach are the source of the generation and transformation of qi and blood; if transportation and transformation are weak, then the generation and transformation of qi and blood are insufficient; overwork, in turn, directly consumes qi, forming a situation of "insufficient supply and excessive consumption."
II. Where the Bladder Meridian Runs Is Exactly Where Cracking Commonly Occurs
The Lingshu · Jingmai records the Foot Taiyang Bladder Meridian as follows: "It begins at the inner canthus, ascends to the forehead, and meets at the vertex." The two words "meets at the vertex" refer precisely to the highest point of the crown. The Bladder Meridian descends along both sides of the human back and is the longest yang meridian in the body, known as the "Great Yang." It governs the exterior of the whole body and manages the body's outermost defensive function. What relation does this have to cracking on the crown of the head? A great deal — when defensive qi is insufficient, the skin loses protection, the six pathogenic influences easily invade, and the skin itself also lacks internal nourishment.
The original text of the Lingshu · Jingmai: "The Bladder Foot Taiyang vessel begins at the inner canthus, ascends to the forehead, and meets at the vertex." When the taiyang meridian qi is abundant, qi and blood can smoothly spread to the crown of the head, and the skin is moist and lustrous. When the body is fatigued and taiyang meridian qi is insufficient to distribute to the highest point, this "distant end" at the crown of the head is the first to show dryness, cracking, tightness, and scaling, just as the terminal canal section of a water project dries up because the water volume upstream has decreased.
The time period corresponding to the Bladder Meridian is the shen hour, that is, from 3 to 5 p.m. This period is when taiyang meridian qi is in command, and it is also the turning point when the body's yang qi begins to decline from its peak and needs to replenish energy. Many people with cracking on the crown of the head often experience obvious fatigue and decreased concentration during the shen hour. This is not simply "having worked too long," but the body reminding them: taiyang meridian qi is already insufficient. In traditional health cultivation, it is advisable to take a short nap during the shen hour, or sit quietly and regulate the breath, giving yang qi a gentle "relay," rather than relying on coffee to force oneself through.
Moxibustion is a commonly used method among the external therapies of Chinese medicine and may be helpful for headaches of a deficient-cold nature and loss of nourishment of the scalp. Along the Foot Taiyang Bladder Meridian there are many back shu points that communicate with the qi of the zang-fu organs. However, which acupoints to choose, which moxibustion method to use, and for how long must all be determined by a licensed Chinese medicine practitioner according to the individual's constitution as a specific plan; one must not copy the operation oneself, and even less should one attempt it blindly with the mindset of "the bigger the better" or "the longer the better."
The core of care during the shen hour is not doing anything grand, but "stopping." If conditions permit, briefly closing the eyes and resting the spirit for about a quarter of an hour during the shen hour is more valuable than making up sleep in the evening. This is also the subtlety of time-based health cultivation — complying with the rhythm of meridian movement and "giving a supporting hand" at the key moment when qi movement passes through, rather than waiting until it is completely depleted and then "patching the hole."
III. When "Clear Yang" Cannot Rise to the Crown of the Head, Nourishment and Distribution Become Empty Talk
In the Suwen · Yin Yang Ying Xiang Da Lun, there is a profoundly meaningful statement: "Clear yang emerges from the upper orifices; turbid yin emerges from the lower orifices." Clear yang is the essence qi of the human body; it moves upward, nourishing the eyes, the nasal orifices, the brain and marrow, and the scalp and hair. If clear yang qi fails to rise and is instead obstructed in the middle and lower jiao, the head becomes the "last mile" of nutrient delivery, and the first to dry up is the scalp at the farthest end.
The original text of the Suwen · Yin Yang Ying Xiang Da Lun, Chapter Five: "Clear yang emerges from the upper orifices; turbid yin emerges from the lower orifices." This describes the basic picture of the ascending and descending movements of qi in the human body. The upper orifices include the ears, eyes, mouth, and nose, and also include terminal tissues such as the scalp and hair roots. When clear yang cannot rise, the lower limbs may feel heavy, while the crown of the head shows another manifestation: not "moistening" but "dryness." Therefore in clinical practice the concept of "raising the clear and lowering the turbid" is emphasized, that is, allowing nutrients that should go up to rise smoothly, and metabolic waste that should go down to be discharged smoothly. This is completely different from "drinking more water" or "applying more moisturizer" — the former is endogenous nourishment, while the latter is exogenous covering.
From the perspective of the meridians and zang-fu organs, the zang-fu most closely related to raising the clear are the spleen and stomach and the liver and gallbladder. The liver governs free coursing and regulates the smooth movement of qi, while the spleen governs raising the clear and transforming and transporting the essence of water and grain. If dryness of the crown of the head that worsens after fatigue is further accompanied by emotional vexation and greater stress, it often also involves hidden depletion of liver blood, making the symptoms more complex. At such times, overly rich and cloying tonics should not be chosen, lest qi movement become obstructed — tonifying without free flow.
What kind of dietary texture and state is more suitable for this group of people? In principle, foods that are warm, moistening, easy to digest, and do not hamper the stomach are advisable, such as congee, soups, and thick soups, while raw, cold, and cooling foods that directly damage spleen yang should be avoided. Traditionally there is the saying that "the five grains are for nourishment" — rice congee, wheat foods, and other five grains are transformed by the spleen and stomach into refined essence qi, which rises to nourish the head and face, and their effect is far more substantial than concepts such as simply "collagen." Emotionally, excessive rumination should be reduced; rumination damages the spleen, and when the spleen is weak, there is no source for the generation and transformation of clear yang. This is also one reason why people who ruminate excessively often have a haggard complexion and dry skin and hair.
The most common misunderstanding at this stage is equating "tonifying" with "eating tonics." Although substances such as donkey-hide gelatin and prepared rehmannia can tonify blood and nourish yin, their nature is sticky and cloying; if the spleen and stomach's transforming and transporting capacity is insufficient, they instead stagnate the middle jiao and hamper the stomach so that it cannot transform. In clinical practice, "move first, then tonify" is emphasized, that is, first get the spleen and stomach moving, then consider the matter of supplementation. Rather than asking "what should I eat to tonify," it is better first to ask "are the spleen and stomach's receiving, holding, transforming, and transporting functions normal?" This is also the embodiment of Chinese medicine's idea of "treating according to the individual."
IV. Self-Observation Directions: Cracking on the Forehead, Crown, and Back of the Head Each Has Its Clues
Chinese medicine diagnosis values the differentiation of disease location. For skin dryness and cracking that occurs on the head, different locations involve different meridians. The forehead belongs to yangming, the exact center of the crown belongs to the Governor Vessel and jueyin, and the back of the head belongs to taiyang. If the entire crown together with the back of the head feels tight, dry, and cracked, it often indicates insufficiency of taiyang meridian qi; if it is most obvious at the very center of the crown, near what is commonly called "baihui," then one should consider more the problems of the Governor Vessel and the liver meridian. This method of differentiation is more targeted than vaguely saying "dry scalp," and also provides licensed Chinese medicine practitioners with more precise clues for pattern identification — this is the first step of "treating the same disease differently."
The Suwen · Sheng Qi Tong Tian Lun has a sentence that provides a good annotation for this phenomenon: "As for yang qi, with vexation and exertion it expands." After vexation and exertion, yang qi expands outward; after expanding, it becomes exhausted — this is also a state of deficient-type hyperactivity, in which a person feels fatigued yet finds it hard to fall asleep. When this state accumulates repeatedly, the skin of the head gradually loses nourishment. This is much more complex than simply "being tired" — it is not something that can be recovered from with one sleep, but rather requires adjustment over a period of time and rhythm.
The original text of the Suwen · Sheng Qi Tong Tian Lun, Chapter Three: "As for yang qi, with vexation and exertion it expands." "Expands" refers to yang qi surging outward while its root is consumed internally; this is a deficient state of "outwardly strong but inwardly dry." This also explains why many people with cracking on the crown of the head instead have difficulty falling asleep after fatigue, or although they sleep a lot, their dreams are chaotic and they feel drowsy on waking. At this time the direction of regulation is not "clearing heat with bland foods," but "calming the spirit and stabilizing the will, securing and protecting yang qi," so that yang qi can withdraw, hide, return to its root, and recover its mandate.
From the perspective of daily rhythm, this group of people should pay special attention to evening rest, especially reducing high-intensity mental activity after nightfall. Yang qi needs to be stored and hidden with the alternation of day and night; not resting at night is equivalent to continuously pulling yang qi out "on duty." Over time, the exterior defense becomes insecure, and the skin and hair naturally lose nourishment. It is worth mentioning that gentle body practices such as daoyin have a positive effect on improving qi and blood circulation; the slow movements combined with breathing in baduanjin and taijiquan help qi movement rise without dissipating, but the specific practice method should be carried out under professional guidance, and one must not excessively pursue "quantity" and "duration."
From the perspective of self-observation, one can observe several seemingly unrelated bodily signals: depth of sleep, mental state, and whether bowel movements are smooth — these are all windows into the overall state of qi and blood movement. If cracking on the crown of the head is accompanied by mental fatigue, loose stools, and fear of wind, it indicates that qi deficiency predominates; if it is accompanied by dry throat and mouth, heat in the palms and soles, and night sweats, it suggests that yin-blood insufficiency accounts for a larger proportion. These are entry points for observing the body, not conclusions. Whether regulation is ultimately needed and how to regulate should be discussed at a regular medical institution with a licensed Chinese medicine practitioner and judged through the combined reference of the four examinations; do not draw conclusions on your own based on a single symptom.
Have you ever thought that dry, cracked skin on the crown of the head that repeatedly fails to heal may not just be a skin disease? It may be reminding you: that upward-rising qi has already been silently consumed for a long time.

I. What causes worsening after fatigue?
Chinese medicine holds that worsening after fatigue should be approached through holistic pattern identification, using the combined reference of the four examinations — inspection, listening and smelling, inquiry, and palpation — together with individual constitutional characteristics for comprehensive judgment; it cannot be generalized. The specific direction of regulation must be determined by a licensed Chinese medicine practitioner after an in-person consultation.
II. Where the Bladder Meridian runs — how long is the regulation cycle?
The regulation cycle varies from person to person and is related to factors such as the individual's constitutional foundation and the degree of cooperation with lifestyle habits. Chinese medicine emphasizes gradual progress; the specific cycle must be assessed by a licensed Chinese medicine practitioner after an in-person consultation according to the individual's situation. This material does not provide commitments regarding a specific cycle.
III. When "clear yang" cannot rise — what should be noted in daily life?
In terms of daily care, it is recommended to maintain regular routines, a balanced diet, moderate exercise, and emotional stability. Specific precautions should be flexibly adjusted according to individual constitution and seasonal changes; targeted advice may be obtained by consulting a licensed Chinese medicine practitioner.
