Hair turning gray and falling out, What is the reason for this? And what is the way of salvation?

Many people are asking for suggestions about hair loss. I presented my study in this regard. No gimmicks or unscientific treatment methods are mentioned here and no one should suggest them. If anything is left out, mention it in the comments.

There are many reasons for hair loss, first you need to know the reason. In this case, if you go to the doctor and check the blood and the skin of the scalp, you will be sure about the cause.
1) If due to malnutrition or any vitamin, vitamin supplement will be given in the beginning. For example: biotin, vitamin A, E supplements, antioxidants. Iron or zinc supplements can also be given.
2) If there is dandruff, shampoo rich in Kitoconazole, ZPTO(Zinc pyrithione), Tar, Salicylic Acid will be given.
3) If the reason is genetic, it will be detected in DHT(Dihydrotestosterone) level in blood test. Treatment is different for MPB or male pattern baldness. If someone else in the family is bald, MPB is more likely if the pattern of hair loss is on the front sides of the head and on the back of the head.
4) In case of MPB, Minoxidil can be used on head along with Finasteride tablet. They act as DHT inhibitors. They are usually taken for a long time and when stopped, hair loss starts again. Minoxidil can be used on its own but Finasteride cannot be taken without doctor’s advice, its side effects can cause various hormonal problems including loss of sexual ability. These two are the only FDA approved medications for MPB.
5) In addition to medicine, there is micro needling as an invasive method. When the scalp is punctured with a derma roller (0.2-1mm) with a small needle, white blood cells are deposited on the scalp to heal the wound and help repair damaged hair follicles. You can buy a 0.5 mm roller and use it yourself. If it is more than that, you have to go to the doctor and get it done under anesthesia.
6) PRP can be done, it takes blood from the body and separates platelets or white blood cells from it and injects it directly into the scalp. It works much like a micro needle but in a better way. In this case, you must consult a doctor. In both cases of micro needle and PRP, when the root of the hair is completely destroyed, the hair does not grow anymore. Only damaged roots can be healed or prevented. In the beginning 1/2 times for 3/4 months and then 2/3 times a year should be continued.
7) Hair transplant is the most effective treatment if the root of the hair is completely lost and there is a lot of baldness. In this case, a good hair root is taken from the side or back of the head and transplanted on top of the head, then hair grows there permanently. Approximately 70-80% of transplants survive, depending on the method.
7) There is also some evidence of benefit from scalp laser (LLLT) but it is very limited.
8) Silicone, SLS free shampoo can be used on the head, normal shampoo should be avoided. Because silicone beads enter the root of the hair and cause irritation, resulting in itching and swelling of the root and hair loss. Again, if you don’t use shampoo, oily hair roots will increase hair loss. It is better not to use oil or anything like that on the hair. Even after use, shampoo should be kept dry immediately. Cold water should be used instead of hot water.
9) Ketoconazole shampoo works as a DHT blocker so use 2/3 times a week to get some benefit. You can also buy a 0.5 mm roller and do micro needling at home 2/4 times a month. In my opinion it is better not to use minoxidil in the beginning. If these don’t work you can try.

No matter what you do it will take 3/4 months to realize the results. Till this time you have to continue with patience. Many people will say that it is better not to put many things on the head because there is no scientific evidence for this, but there is a lot of evidence that these things increase hair loss. Keep the root of the hair as dry as possible and wash it with shampoo if you sweat. Definitely don’t use normal shampoo.
