(Distinguished from hair coloring - there are many people say that the color baked oil, this is not true, all professional brands do not say that their color is baked oil!) Frequent oil baking is necessary!!! But daily washing and care is more important!!! For hair care, especially after perming and coloring, daily professional washing and conditioning is of course a must!!! In addition to this, regular oiling of the hair is also very necessary, it will give the hair the necessary nutrients, so that the hair grows healthily! Especially for permed and dyed hair, oil baking is of course better, you can use a special baking oil for post permed/post dyed hair. And baking cream can improve the quality of your hair, of course, there are good and bad baking creams, depending on the kind you want to choose. I know the better baking creams (professional ones) are Chi Choi's Amino Acid Baking Cream, and Wella's Yunlu. Baking oil cycle - two weeks to do a baking oil, not very frequent! But don't increase it! In fact, the frequency of oil baking is based on your own analysis of the texture of the hair, to give extra care to the hair! It is advisable to pay more attention to your daily washing and care at home! There is no harm in too much oil baking, but it won't be any better about oil baking at home: if you want to buy your own oil baking to do at home, you need to buy a professional brand, such as Wella, Black Head, L'Oreal and so on. As to whether two or three hundred dollars can buy professional products is hard to say, depending on whether you will buy. Anyway, this method is feasible.
