What does a healthy perm and hair dye pull mean?

That is, the damage to the hair is small and will not be damaged. That's what your hair looks like before it's dyed, and it still looks like that after it's dyed. That is to say, the hair quality will not be damaged basically, but most ordinary hair dyes can't achieve this effect. The damage of ordinary dyeing is still serious, even after dyeing, the hair will be dry and short-tempered, like hay. In other words, healthy hair dyeing is a healthier way, and the damage to hair accessories is also relatively low.
