There are differences in the way thinning hair progresses depending on the type, such as thinning on the top of the head or at the hairline. Please observe the characteristics of the thinning hair progression you are interested in and check which type you fall into.
First, let’s identify the type of thinning hair
There are three main types of thinning hair, and the location of hair loss differs depending on the type.
The hair at the hairline becomes thin and weak, and the front part of the hair falls back so that the hairline rises from the left and right corners of the forehead, which is called the “M-shape.
The “U-shape” is a type of hair that was originally “M-shape” but has become serious due to the progression of thinning hair, and requires early countermeasures.
What are the causes and countermeasures for M-shaped thinning hair on the forehead?
M-shaped thinning hair that grows up from the forehead tends to be caused by male alopecia areata (AGA), a thinning of the hair that is unique to men. It may also be due to mechanical hair loss caused by continually applying force in the same direction to the hair and scalp, such as when the hair is grown long and tied back.
In the case of AGA, the amount of sebum secreted from the pores of the scalp increases, so avoiding greasy foods in the diet and carefully shampooing the hair while massaging it are countermeasures. In the case of mechanical hair loss, it is advisable to change the hairstyle to avoid continuing to put the same form of strain on the hair and pores.
What are the causes and countermeasures for O-shaped hair that is thinning like Kappa?
O-shaped hair loss, which spreads from the whirlpool to the entire hairline, is also a male-specific type of hair loss that is often associated with heredity, as dihydrosterone secretion tends to affect hair loss on the top of the head.
If hair thinning from the top of the head progresses, there is a risk that the forehead and the area of hair loss from the whirlpool may become connected, so it is advisable to start using hair growth products as early as possible. It is recommended to consult a dermatologist before using a hair-growth agent containing minoxidil, an ingredient that is known to cause hair growth.
If hair loss is accompanied by dandruff and itching, it may be seborrheic alopecia, and in this case, too, consult a dermatologist.
How do you deal with U-shaped thinning hair that has progressed?
U-shaped hair loss, which extends from the forehead to the crown of the head, is caused by either M- or O-shaped hair loss that has progressed. It is recommended that care be taken both externally by improving one’s lifestyle and externally by using hair growth products.
In terms of diet, avoid eating foods high in salt and fat, such as instant foods and fast foods, and include in your diet amino acids and zinc, which are necessary for hair production. Quitting smoking and getting enough sleep can also be effective in normalizing the hair cycle. External care involves removing unnecessary sebum from the scalp and continuous use of hair growth products.
In both cases of hair loss, it is possible to delay or improve the progression of hair loss by starting measures early. Please start taking care of your hair according to your type.
