Male Pattern Baldness in Focus: How DHT Affects Hair Loss!

Male Pattern Baldness in Focus: How DHT Affects Hair Loss!

The feeling is overwhelming while one faces hair loss problems and looking for reasons that could be of wide arrays such as bad diet, medication, changing hairstyles, chemical cosmetics, inherited genes and so on.

All might be true…!

But, primarily hair loss in men and women is caused by DHT (Dihydrotestosterone) that is a male steroid hormone, is the reason for male sexual characteristics and binds the receptors on the scalp. Imbalanced DHT may cause heavy and permanent hair loss.

The overall concept of DHT is complicated since its relation to hair loss is easily recognizable. In the blog, we would help you in understanding how DHT is produced in your body and effect of DHT in on hair follicles.

Defining DHT-

– DHT abbreviated form of Dihydrotestosterone is a powerful male sex hormone that is a byproduct of testosterone. DHT is an androgen that is responsible for male sex characteristics and things like producing male genitalia during pregnancy.
– In simple words, DHT is one of the hormones that make a man. Also, It is different from other sex hormones like testosterone.
– As we know DHT is a byproduct of testosterone. 5α-reductase is an enzyme that is responsible for the metabolism of androgen, estrogen and bile acid. 5α-reductase enzymes convert a certain part of testosterone into DHT for skin, liver, prostate and hair follicles.

Relation of Hair Growth With DHT-

– If your hair loss is genetic then at some age DHT can start the process called ‘Miniaturisation’ where your DHT binds the receptors and cause hair follicles to shrink, weaken and even die.
– DHT is a reason behind the development of Male/Female Pattern Baldness (Androgenic Alopecia). Although, is also the main factor to hair growth in areas like chest, beard, back and other areas.

DHT Affects Hair Growth Cycle-

Hair growth is followed by a cycle that has 4 stages. Each hair passes through these stages. They are as follows-

  • Anagen phase (Gowing Phase)– hair starts to grow initially- 2-7 years
  • Catagen phase(Transition Phase)– hair follicles get shrunk and hair move upwards to base- few days to a week
  • Telogen phase( Resting Phase)– Old hairs stay in rest and new hairs begin to enter growing phase- 2-4 months
  • Exogen phase(Shedding Phase or New Hair Phase)– Old hairs starts shedding and new hairs continues to grow
  • Anagen phase (Gowing Phase)– hair starts to grow initially- 2-7 years

Doctors consider 50-100 hair shedding every day as normal but more than it could be a sign of hair loss.

DHT affects the growth of hair as it increases the miniaturization process of hair follicles. In hair loss anagen phase reduces and telogen phase becomes stronger means growing phase is shorter and hair can not grow long as before.

Over time, anagen phase becomes shorter and hair stops coming out of the base or surface of the skin and telogen phase causing more than usual hairs to fall.

If not treated, with each hair cycle follicles become smaller and hair thinner. Hairs turns into vellus hairs (short, thin, light and unshiny) that might disappear response to imbalanced androgens.

So, DHT affects the hair growth and may cause temporary or permanent baldness. It has many treatments such as medications, PRP, hair transplant and more.
