The "regain" thingy as suggested by someone in the thread has "minoxidil" in it.. It is an arterial dilator.. Basically it dialates the arteries supplying blood to your scalp skin, helping the hair take more nutrition; and therefore better growth and less hairfall.. But the problem with that particular drug is that it takes a little long to show its effects.. So if you ever try it, dont lose hope very soon and think that its not working.. It takes anywhere from 4-8 months to show effects.. It has no particular side effect and its pretty much safe to use... The only problem being the changes will revert back soon after you stop applying it.. The effects are
NOT permanent..
Also male pattern baldness is due to high levels of testosterone(Mainly Dihydro-testosterone : DHT) .. There are some drugs that inhibit the conversion of testosterone to DHT.. Most commonly used drug being Finasteride.. But Finasteride being a 5-alpha-reductase inhibitor(inhibits conversion of testosterone to DHT) will have side effects mostly pertaining to ummm "your dong"... So if you are a young male, I wont advise you to go for it ever...
Anyway now coming to the remedy of sorts..
1) Keep your scalp always from chemicals/detergents etc.. Use mildest possible shampoo...
2) Eat one walnut a day.. It has almost the same effect as finasteride ; minus the side effects...
3) 1cashew + 1almond + 1dry fig a day before sleeping( more will not help, if you are wondering )
4)Vitamin supplements may help.. Vit D and C both...
5) Ultimate option is to go for hair transplantation...!!
Lastly : If its male pattern baldness you are suffering from.. No hope for you my friend... Its in the genes... No drug is powerful enough as yet in medicine which can change whats written in your DNA.. It has to happen and it will happen no matter what..!!
Learn to live and enjoy baldness..!!
PS : Pm me if u need any clarification on the matter.. I am a doctor myself.. Will be glad to help..!!
