From my own experience, I can say that the most effective and useful oils for hair are: argan, castor, coconut and avocado. From burdock no effect, to be honest. But it is the most popular. May not suit me personally. Regarding the application: heat the oil in a water bath (you can mix several oils), apply to the hair (not to the scalp!), Put on a plastic cap and a terry towel. And leave all this beauty for at least an hour. Someone leaves for the night, but it seems to me that an hour is enough for the hair to "take" all the most useful from the oils. Another very effective mask with dry mustard or red pepper extract. BUT, this will work for you only if the scalp is not sensitive or dry. Good luck! Luxurious curls for you💁🏼
Warm up the burdock oil (leave the bottle of oil in hot water) and then apply to your hair, wrap your head with a towel for two hours. Then wash your hair with regular shampoo. Do this mask twice a week (although one is enough) and your hair will grow faster and become healthier. Itself only with burdock oil I make a hair mask (grow !!!), cheap and effective. I don't know any other effective masks that promote hair growth, like the wonderful burdock oil.
