A powerful androgen hormone produced from testosterone is called dihydrotestosterone (DHT), also a significant factor for hair loss 

DHT blockers are substances designed to inhibit the conversion of testosterone into DHT 

By reducing DHT levels, these blockers help prevent hair follicles from shrinking and can potentially reverse hair thinning. 

Popular DHT Blockers are Finasteride, Dutasteride and Natural DHT Blockers. These help in reducing hair loss and increasing hair growth

Before starting any DHT blocker, it is advisable to consult with a healthcare professional to stay safe from its potential side effects
