I would like to ask more questions. 1. Between
Pure Keratin™ with
Panthenol (Vitamin B5) ExtraLite , which one is more effective in nourishing hair? or how is it different I don't know if you can use them together. 2. Then should use
Pure Keratin™ in what ratio is it suitable for hair mist? (Probably 1-2% right?) 3. Both
Pure Keratin™ and
Panthenol (Vitamin B5) ExtraLite is soluble in water. Show that in the mix must be used
น้ำกลั่น to mix with the hair treatment first. and then mix with the head
น้ำหอม +
Ethyl Alcohol right? If yes, don't know how many % water should be used to dissolve
Pure Keratin™ and
Panthenol (Vitamin B5) ExtraLite 1%, please help me, I'm really newbie and thank you so much ^^
