Why does someone dye their hair and look bright? why

Hello, landlord? It's an honor to answer your questions? I hope my answer will make your life better!

First of all, let me tell you with 10 years of hairdressing professional education career? Different hair quality+different dyeing products+different post-dyeing care = different effects?

When you say bright after dyeing, do you mean shiny after dyeing your hair? Gloss = the closing degree of hair scales (hair scales refer to the outermost skin of hair, as shown in the figure) = the health degree of hair.

So what? What about healthy hair? What kind of hair dyeing products do you choose? Plus long-term care of acid shampoo and conditioner after dyeing hair? = = Best hair dyeing effect

But what about unhealthy hair? More impetuous? Fuck? What if? If you want to dye your hair? It is recommended to choose hair dyeing products with partial care.
