Flaxseed oil contains vitamin E, which promotes the growth of new hair and treats hair loss. Strong antioxidants like lignans can aid to regrow healthier and stronger tresses. Flaxseed is a rich source of essential nutrients like omega-3 fatty acids, vitamins B and E, and proteins. 
These nutrients promote hair growth and improve scalp health. 
Incorporating flaxseed into your diet or applying flaxseed oil and gel to your hair may have positive effects on hair growth. 
Flaxseed may help balance scalp pH levels and regulate oil production.
