hey bro have some tips on how to hold on to your strands as long as possible. Losing hair can be a big array of things but due to this being on a fitness board I will assume its androgenic alopecia related. so follow this and you might hold on to them longer or might grow some back( hopefully)
Get your hands on these different shampoos
1. Alpecin caffeine shampoo
2. Rogaine shampoo (think its monoxidil)
3. Kez 20mg(Ketoconazole) shampoo
Now all three of these work through different pathways but hence working out a protocol that will work. i'll go over how they work quickly, alpecin contains caffeine and small studies showed it increased hair growth rate, not new hair just old hair growth rate, this is important due to the fact that hair that grows rapidly has a well nourished follicle and will thus be stronger = less falling out. Secondly Rogaine(only FDA apprpoved shampoo for hairloss) will increase nourishment to these follicles and allow needed nutrition to the scalp and improve overall follicle health and strength = less hair falling out,stronger follicles.Lastly Kez shampoo contains ketoconazole, this compound was initially intended to treat dandruff and fungal manifestation on the head, in the studies they found that some participants who suffered from androgen alopecia had halted the process and some of the patients actually had some hair growth back, method of doing is too long to explain but basically they found it blocks dht to the hair follicles but doesn't have the systemic effect such as with propecia, but remember it only worked for some so its a hit and miss.
This will only work for the clean

, if you shower 2 a day which you should apply either rogaine or alpecin in the mornings let it on and rinse,and in evenings apply the Kez. Do this religiously and I can assure you your balding will slow down significantly. Key is to take care of the hair as you do any other part of the body
Now this isn't some miracle solution nope, but it has worked for me, my hair is still where it was about 2 years ago and hope to keep it as such, although eventually genetics will do its thing, but for us gear oaks , we should take care of our hair.
Also big lover of tren, haha but tren loved removing my hair. So stay away from harsh compounds that affect dht if you value hair above gains....(laughing as I inject another cc of tren)
