thanks for writing to us.Hair fall
in your age group is not so common.
Most common cause in this age group for hair fall is dandruff
.You need to apply a good antifungal shampoo like ketoconazole
.Use it twice weekly.
Do not use any styling gels.They will further cause damage to your hairs.Start taking multivitamin
tablets contaning biotin for 2 to 3 months.
You can use a hair serum (like dove).it is rich in proteins.it will help you in styling your hair and will nourish your hairs.
Hope this can solve your problem.Take care.
