Hello If u have hair fall u should not do any straightening treatments as they will cause more hair fall.you should get your blood test done for vit B12 vit D3 and serum ferritin and hormonal check if period are irregular. After you get these corrected and you can also start on oral biotin supplement like tab keraglow Eva once a day for 3 months. And hair spray like quilib hair spray twice a day 10sprays. For smoothening treatments do cystein treatment as it doesn't not damage the hair root. Hope this helps Best Dr Batul Patel Www.Drbatul.com
