저도 모발이 얇아져서 속상하네요
My hair is naturally thin and weak, so I am worried because even if I try to add strength with a perm or a curling iron, it loses its volume quickly.
When I dye my hair, it gets damaged faster than others...
Oral nutritional vitamins, topical nutrients, treatments, etc. that are good for such thin and weak hair
Please recommend several.
