Many men in Surat face hair loss due to testosterone levels. Most of them visit a hair transplant clinic in Surat for hair transplant surgery to prevent baldness. However, do you know why men face hair loss in their thirties and forties? Let us learn about one particular hormone in men that is directly responsible for hair loss. 


Testosterone – how does it cause hair loss? 

Testosterone is a male sex hormone. It is helpful for many purposes, involving the development of secondary sexual features in males. A high level or very low of this hormone causes hair loss. Here is how it works

Your body hair grows with the help of follicles. Follicles are tiny pores below your skin that contain a hair strand. The strands have a growth cycle of two to five years, after which they reach a resting stage and fall. 


High androgen levels in your body produce a hormone called Dihydrotestosterone (DHT). DHT binds to few proteins inside your body, which in turn reduces your hair follicle’s size. It results in the hair’s thinning and may delay the growth of fresh hair strands. 


Both low and high levels of testosterone can cause hair loss. Men with low testosterone levels may have a similar quantity of DHT that leads to hair loss. Furthermore, men with male pattern baldness have low testosterone levels with average DHT levels in their bodies. 


Few men have a similar DHT quantity, yet their hair follicles are genetically sensitive to DHT. It makes your follicles more vulnerable to the DHT. 


Androgenetic alopecia in males is because of changing testosterone levels and genetics. In men, it occurs in a specific pattern that results in complete balding. 


Frontal baldness is the beginning of androgenetic alopecia for males. It begins from your temples, then progresses to complete balding. It is the reason why most men go for hair transplant treatment in Surat


How to treat hair loss caused by fluctuating testosterone levels? 

Several medicines have proved to be efficient in treating your DHT hair loss. The medications are of two categories – inhibitors and blockers. 


DHT blockers are medications that prevent it from mixing with the five alpha-reductase enzymes. DHT inhibitors help reduce the production of the hormone. 



Finasteride is an oral medication that may be effective in treating your balding. Research suggests that finasteride has an eighty-seven percent success rate in hair redevelopment in males. The remedy blocks and binds to the five alpha-reductase enzymes to stop the DHT hormone from affecting your hair follicles



Minoxidil blocks DHT. It was a medication given to patients who had increased blood pressure. As a side-effect, some patients started to have extra hair growth. 


This medication assists in expanding your blood vessels to enhance the flow of blood. When you apply topical minoxidil, it can increase blood flow to your hair follicles, hence improving its growth. 



Vitamin B derivative is Biotin that turns nutrients into energy, which your cells utilize to do their functions. Studies suggest that Biotin improves your hair growth and prevents hair loss. 


B Vitamins 

B vitamins are important to keep your scalp and hair healthy. Insufficiency of these vitamins may reportedly result in hair loss and hair thinning. They improve the blood flow to your hair follicles. B vitamins may not help in hair growth; however, they can stop hair loss


If the above-mentioned medicines do not work you can go to consult a hair transplant doctor in Surat and learn more about the procedure. 


Side-effects of DHT blockers and inhibitors 

Few side effects of DHT blockers involve: 

  • Erectile dysfunction 
  • Ejaculating too early Rashes 
  • Feeling sick 
  • Vomiting 
  • Ejaculating too late 
  • Excess fat around the breast area 
  • Darkened hair on the face 
  • Heart failure 

If you have any of these signs, speak with your specialist about alternatives. Hair fall that is caused because of changing testosterone levels is linked to baldness. 


Few men are genetically sensitive to dihydrotestosterone, whereas other men have high levels of the hormone. Proven medicines to block DHT from binding to your hair follicles can prevent hair fall. Yet, if your baldness is extra, it is best to go for a hair transplant procedure.
