Personally, I think that protecting hair through nursing can only maintain the current situation of hair, but it can't greatly improve hair. If you want to make your hair better, you can only care for the hair follicles and make the new hair brighter.

When choosing shampoo and conditioner, try to choose the same type of the same brand, which will not cause great stimulation to the hair, but also allow the hair to get proper care.

You can also use a hair mask once if necessary. Compared with conditioner, hair mask can bring supple effect to hair for a longer time and make hair look better.

I've seen it before, saying that washing your hair with beer can care for hair follicles and make new hair look better. I haven't put it into practice. If you think it is necessary, you can try it.

During hair care, avoid damage to the hair, and try to avoid dyeing and perming. Only natural hair can maintain beautiful color, and modified hair will always be dull.
