21 year old with rapid hair loss
It is important for you to see a specialist for hair in your area that can examine your scalp and hair. Your hair loss could be as a result of an underlying medical condition, use of medication, natural shedding, or genetic predisposition to hair loss. Unfortunately there is no way to know over the internet and thus the recommendation to see a local physician that specializes in this field.
Thank you for your question. You will need a plan that should involve a Board Certified Dermatologist, a Registered Dietician, and evaluation by an internal medicine specialist to determine if any other testing is required. Be certain to be getting high quality protein, quality carbs, and quality fats every day. Excessive shampooing and harsh shampoos have a negative effect on hair growth. Find one recommended by your dermatologist. I hope this helps!

There is nothing as important as a proper diagnosis and early treatment. You need to find a good hair specialist who can perform a scalp and hair microscopic evaluation. You may also need some lab works to make sure there is no other medical condition responsible for your condition.
