I have been researching how herbs can help with hair health .
Olive oil and rosemary apparently will help prevent premature grey hair as well as soothing dry and itchy scalp.
Peppermint oil on the scalp has a cooling effect which may stimulate growth
Onion juice apparently stimulates growth and stops breakage. Boil onions and strain it and use it as an after shampoo rinse. I assume with conditioner , I am trying it now so I will keep you posted.
Sage is also excellent for hair growth
