Oily Scalp at the Front, Thinning on Top — Two Different Stories on One Head
Where the oil sits and where the hair goes are separate questions, and the tradition answers them differently.

Quick answer
Chinese medicine reads a greasy hairline and thinning at the crown as two separate patterns. Front-of-head oiliness sits on the stomach channel and points to damp-heat in the digestion; thinning at the crown relates to the deeper reserve. Most men have some of both, in different proportions.
Two Things Happening on the Same Head
Men usually describe this as one problem. Hair is thinning and the scalp is greasy, so presumably the grease is causing the thinning, and the answer is a better shampoo.
When you look more carefully there are almost always two separate things going on, in different places. Grease and itchiness at the hairline and forehead, often with flaking. And separately, hair that is visibly thinner at the crown, which is a slow, quiet change over years.
They usually behave differently too. The oiliness responds to what you ate and drank last week — a run of takeaways, a heavy weekend, hot humid weather. The thinning does not respond to anything on a weekly timescale.
That difference in timing is the first clue that you are dealing with two stories rather than one.
How Chinese Medicine Reads It
Start with the map. The Lingshu chapter "Jing Mai" (《灵枢·经脉》) traces the Stomach channel up over the face and forehead, and the front of the head sits in what the tradition calls yangming territory — the stomach and intestines.
That is why front-of-head oiliness is read as a digestive matter rather than a skin one. Rich, fried, sweet food and alcohol generate what the tradition calls damp-heat, and damp-heat rises and expresses itself where that channel runs: a greasy forehead, a greasy hairline, flaking and itching.
The supporting signs are consistent. A yellow greasy tongue coating, a bitter taste in the morning, urgent or loose bowels, strong body odour, and everything worse in humid weather or after a weekend of beer and barbecue.
The crown is a different territory. The Suwen chapter "Liu Jie Zang Xiang Lun" (《素问·六节藏象论》) says of the Kidneys 其华在发 — their outward flowering is in the hair. And the Suwen chapter "Shang Gu Tian Zhen Lun" (《素问·上古天真论》) puts the male turning point at 五八 — forty — with 肾气衰，发堕齿槁: kidney qi declines, hair falls and teeth lose their lustre.
So the crown relates to the deep reserve — sleep, overwork, chronic late nights, years of pushing on — while the hairline relates to what has been going through the digestion lately. Different timescales, different plans.
The points follow the split. For damp-heat: Fenglong ST-40 ("Abundant Bulge") midway between the outer knee eye and the outer ankle bone, and Yinlingquan SP-9 ("Yin Mound Spring") below the inner knee. For the reserve: Shenshu BL-23 ("Kidney Transport") at waist level, and Baihui GV-20 ("Hundred Convergences") at the crown, where a line between your ear tips crosses the midline.
What’s Real, What’s Myth
Myth: the oiliness is causing the thinning. They frequently coexist and they are not the same process. Plenty of men have a greasy scalp and thick hair, and plenty have a dry scalp and a thin crown. Reading them as one problem is why a better shampoo so often produces a cleaner scalp and no change to the crown.
Myth: washing less will fix an oily scalp. It rarely does, and it usually makes the flaking worse. What does change it, in my clinic, is what goes in the mouth — less fried food, less sugar, less alcohol — over two to three weeks. Men are consistently surprised by how directly the two are connected.
Myth: hair loss is only genetic, so nothing else matters. Pattern hair loss has a strong hereditary component and that is well established. What is also true is that sleep, stress, iron levels and thyroid function all influence how much and how fast, and those are the parts you can influence.
Myth: a scalp massage will regrow hair. Scalp work is pleasant and it may help the local scalp condition. Anyone promising regrowth from massage is overselling it, and I would rather say so plainly than let you spend a year on it.
Real: rapid or patchy loss is a different question entirely. Diffuse slow thinning at the crown over years is one thing; hair coming out in handfuls, or coming out in patches, is something to have looked at by a doctor rather than approached through food.
Six Things You Can Do This Month
1. Work out your proportions first. Is the main complaint grease and itching at the front, or thinning at the crown, or both? The first responds in weeks and the second in seasons, so knowing which you are chasing keeps you from giving up too early on the slower one.
2. For the oily front, cut the source for three weeks. Less fried and rich food, less sugar, and — the one that matters most — less alcohol. In this framework beer is both damp and warming, which is why a heavy weekend shows on the forehead by Tuesday.
3. Add the classical damp-clearing foods. Raw coix seed (生薏米), mung bean and winter melon suit a damp-heat picture, and note that this is the raw form of coix seed rather than the dry-fried one — dry-fried belongs to a cold, heavy picture instead. Getting these the wrong way round is the most common error I correct.
4. Press Fenglong ST-40 ("Abundant Bulge") and Yinlingquan SP-9 ("Yin Mound Spring") for a minute each side. The first sits midway between the outer knee eye and the outer ankle bone, two finger-widths outside the shinbone; the second in the hollow below the inner knee. Both are often notably tender in this pattern.
5. For the crown, work on the reserve rather than the scalp. In bed before eleven, five nights out of seven. Finish training at a light sheen rather than emptied. Warm the low back at Shenshu BL-23 ("Kidney Transport") for two to three minutes daily. This is slow work and it is where the actual leverage is.
6. Tap Baihui GV-20 ("Hundred Convergences") lightly for a minute. Find where a line between your ear tips crosses the midline of your head. Light fingertip tapping, not pressure. Modest and pleasant — and worth saying plainly, not a regrowth method.
When to See a Doctor
Some hair and scalp changes need proper assessment. See your GP or a dermatologist for hair loss that is patchy or in discrete circles, for hair coming out in handfuls, for loss that is rapid over weeks, or for any scarring, redness or scaling of the scalp underneath.
Book an appointment for scalp itching that is severe or not settling, for weeping or crusted areas, or for any sore on the scalp that does not heal — the last one matters and is worth showing someone.
Ask for basic blood work if the loss is diffuse and recent: thyroid function, iron and ferritin, vitamin D, and blood sugar. Low ferritin is a genuinely common and correctable contributor, and testosterone-related questions are worth raising with your GP rather than researching alone.
If pattern hair loss is what concerns you, there are proven medical options and they work considerably better when started early. That is a conversation with a doctor rather than something to postpone while trying food changes — you can do both.
Which Constitution This Usually Points To
A greasy, itchy hairline, a yellow greasy tongue coating, a bitter taste in the morning, urgent bowels, strong body odour and everything worse after a heavy weekend point toward a damp-heat constitution (湿热质). This is the fast-moving half of the picture and the one that responds within three weeks of changing what goes in.
Thinning at the crown alongside a cold aching low back, waking at night to pass urine, knees that complain on stairs and a deep tiredness points instead toward a yang-deficient (阳虚质) or qi-deficient (气虚质) picture. That half moves in seasons, through sleep and reduced spending rather than through any food.
Most men over forty have some of both, in different proportions, which is exactly why one-size advice keeps failing them.

Why is only the front of my head oily?
In this framework the forehead and front hairline sit on the stomach channel, which is why oiliness there is read as a digestive matter rather than a scalp one. It is also why it tracks so closely with alcohol, fried food and sugar over the preceding week or two.
Raw or dry-fried coix seed?
For a damp-heat picture — yellow greasy coating, bitter taste, oily skin — use the raw form (生薏米), which is cooling. The dry-fried form (炒薏米) belongs to a cold, heavy, white-coated picture. Using the wrong one is why people report that coix seed did nothing for them.
Will changing my diet regrow hair at the crown?
I would not promise that, and I would be wary of anyone who does. Food changes act fastest on the scalp condition and the oiliness. Crown thinning relates to a slower picture, where sleep, workload and having your iron and thyroid checked are the parts worth acting on.
Does washing my hair every day make it worse?
Usually not. Men often try washing less and find the flaking and itching increase. A gentle daily wash is fine for an oily scalp; what changes the oiliness itself is what goes in over two to three weeks rather than what goes on.
