The link between Testosterone and Hair Loss

Are you in the age group between forty and fifty? Your hair fall can be due to the fluctuating testosterone levels. Want to know what that is?

Testosterone is a male sex hormone. It is useful for several purposes, including the development of specific secondary sexual characteristics in men. A very low or high level of this hormone results in hair loss.

Is testosterone the cause for hair loss, or is there something else? Let us learn the reasons and methods to treat testosterone hair loss.

High Testosterone Vs. Low Testosterone

Your body hair develops through follicles. Follicles are small pores under your skin that has a hair strand. The strands have a growth cycle of two to five years, after which they approach a resting phase and fall out.

High levels of androgens in the body create a hormone known as Dihydrotestosterone (DHT). DHT binds to some proteins in your body, which in turn decreases the size of your hair follicles. It can result in the thinning of your hair and may delay the development of new hair strands.

Both high and low levels of testosterone can cause hair loss. Men with low testosterone levels may contain the same quantity of DHT that contributes to hair loss. Men with male pattern baldness have low testosterone levels with average DHT levels in the body.

Some men have the same DHT quantity as others, but their hair follicles are genetically more sensitive to DHT. It makes their follicles more susceptible to the DHT.

Androgenetic alopecia in men is due to fluctuating testosterone levels and genetics. In men, it takes place in a particular pattern that can result in complete balding.

How to treat Hair Loss caused by Fluctuating Testosterone Levels?

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

DHT blockers are medicines that stop it from binding to the five alpha-reductase enzymes. DHT inhibitors help decrease the creation of the hormone.

The medicine is a blocker and binds to the five alpha-reductase enzymes to prevent the DHT hormone from affecting hair follicles.

This medicine helps widen blood vessels to improve the flow of blood. When applied, topical minoxidil can help raise blood flow to hair follicles, hence enhancing its growth.
