Self-test
Is this type yours?
- ◎The hairline on both sides of your forehead (the temples) has pulled back compared to before, forming a line that looks like the letter M.
- ◎When your hair is wet or lit from above, your scalp is clearly visible on the crown.
- ◎Your hair strands are finer and softer than before; the same length of hair gives less volume.
- ◎When you compare with old photos, you see a difference at the front and crown.
- ◎Someone in your family, on your father's or mother's side, such as your father, grandfather or maternal uncle, had thinning hair at a young age.
- ◎When you use a hair product, your hair separates into clumps and your scalp shows through the gaps.
In depth
What happens at the root?
The most common cause of thinning hair in men is androgenetic alopecia, or male pattern hair loss. In this condition, genetically sensitive hair follicles shrink a little more with each cycle under the influence of a powerful androgen derived from testosterone. Thick, pigmented strands are gradually replaced by finer, shorter ones; this is called miniaturization. Research shows that in the early stage, the thinning look comes mainly not from fewer strands but from thick strands becoming finer. The process usually starts at the temples and crown and becomes more common with age; in some men it can begin in their twenties.
Sudden, diffuse shedding may point to a different picture: intense stress, serious illness, rapid weight loss or nutritional deficiencies can lead to widespread shedding a few months later. Patchy bald spots require a separate evaluation. The condition of the scalp also plays a part; men with male pattern hair loss have been shown to have a different sebum composition and microorganism balance on the scalp. Cosmetic care doesn't stop the inherited process, but a clean, balanced scalp, the right haircut and light products help hair look fuller. With options used under a physician's assessment, the earlier you start, the more hair can be preserved.
Priorities
What does it need?
01
Early evaluation
When you notice thinning, seeing a dermatologist instead of waiting helps you understand what kind of process it is and talk through your options in time.
02
A clean, balanced scalp
An oily, itchy scalp makes strands look flatter and sparser. Regular, gentle cleansing makes it easier for hair to lift at the roots.
03
Products that don't weigh hair down
Fine strands can't carry heavy products. Light, matte, volumizing products make the scalp less visible.
04
The right haircut
With thinning hair, long, heavy cuts separate into clumps. Cuts that are short on the sides with medium-length, textured hair on top give a fuller look.
05
Overall health
Sleep, stress, diet and smoking can affect the hair cycle. With sudden, widespread shedding, you should see a doctor to have your blood work checked.

Step by step
Your care routine
3 steps
- 01
A scalp-focused wash
Apply a gentle shampoo to your scalp, massaging with your fingertips. Scratching with your nails irritates the scalp.
- 02
As often as you need
If your hair gets greasy, washing every day doesn't increase hair loss; the strands you see while washing are ones that were already in the shedding phase. Clean hair lifts better at the roots.
- 03
Light conditioner, or none
With short, fine hair you often don't need conditioner. If you use it, apply only a small amount to the ends.
What you can add to your routine
The link between sebum and the microbiome
Research has shown that men with male pattern hair loss have a different sebum composition and a disrupted bacteria-yeast balance on the scalp. These findings point to the importance of a balanced scalp; however, the main causes of hair loss are genetics and hormones.
Don't ignore itching and dandruff
An itchy, flaky, inflamed scalp hurts the way your hair looks. If you have dandruff and redness, it's important to address them separately.

Your questions
Frequently asked questions
01Does gel, wax or clay cause hair loss?+
There's no strong evidence that styling products cause inherited hair loss. However, product that builds up on the scalp can cause itching and irritation, and heavy products make hair look thinner. Washing the product out well in the evening is enough.
02Do hats or helmets cause hair loss?+
Hats and helmets don't kill hair follicles and don't cause inherited hair loss. Very tight headwear that rubs constantly can cause traction along the front hairline. Keeping your helmet liner clean and washing a sweaty scalp the same day is enough.
03Does washing my hair every day increase hair loss?+
No. The strands you see while washing are ones that were already in the shedding phase; they fall out on days you don't wash too, you just see them all at once at the next wash. A clean scalp helps hair look fuller.
04At what age does male pattern hair loss start?+
It can start at any age after puberty; in some men it becomes noticeable in their twenties. It becomes more common with age. If early thinning runs in your family, it makes sense to watch for the signs earlier.
05When should I see a dermatologist?+
It's a good idea to see a dermatologist when you notice your hairline receding or your crown thinning, when you have sudden, widespread shedding, or when you have patchy bald spots or itching, redness and burning. With options used under a physician's assessment, starting early helps preserve more hair.
06Can cosmetic products stop hair loss?+
It's not possible to stop inherited hair loss with cosmetic products. The right shampoo and styling product help your hair look fuller and more groomed and keep your scalp in balance. The process itself requires a dermatologist's evaluation.
