想DIY在家漂髮？不想變禿頭請先看看這五個大忌！

來到夏天，第一件事當然是換個新髮型！貪新鮮是女生的天性，看完幾條Youtube片後，不少女生就有樣學樣買染髮劑DIY在家漂染，漂得靚當然要恭喜她們，但漂到甩頭髮的個案還是不少的。為了你的頭髮著想，漂染頭髮前請花五分鐘看看這五個大忌！

#HairBesties, I love to use @guytang_mydentity PERMANENT color in 10RG (Rose Gold) and 9AR (Amber Rose) to pretone prelightened hair mixing 1:2 ratio with 6vol on damp hair adding 1/16 oz @olaplex for up to 20mins before I do a glaze on dry hair with #Mydentity 9RG or 7RG and with Crystal Clear Demi because this becomes an anchor and increase the longevity of #rosegoldhair. The permanent dyes have longevity and the DEMI-Permanent has the shine and dimension. When you couple them, they provide longer lasting color! Also with Guy Tang #Mydentity permanent 1:1 ratio with developer is the standard mixing ratio but the reason why tone it on damp hair mixing 1:2 is to decrease the pH to avoid any base break to the natural hair and also have healthier hair after a prelightening/bleach service. You can also use the NEW #Mydentity XPress Toner Demi on damp hair for 5 mins with 6 vol dedicated developer 1:2 ratio. @lilya_412 one of my models in Dubai, UAE @nazihcosmetics @beautyworldme show. Thanks to my team @arianasin @denisearussell @firaskhalil1 @edolaplex TAG friends who wants this color

1. 漂染前洗髮

染髮前兩天最好避免洗髮，除了可以預防頭髮過乾，也可以讓頭皮分泌出的油脂形成一層保護膜。染髮時加點@opalex 護髮素也可以保護髮絲。

2. 漂太久

一個很簡單但很多人都會忽略的重點。曾經漂染過的頭髮會更容易有開叉和斷裂的情況發生，所以即使頭髮沒有預期中般淺色，也不要直接再重新漂染！

3. 染髮失敗了立刻重染其他顏色

最少給頭髮休息一星期才重新漂染，否則頭髮容易受損，而且上色也不會持久，顏色很快會褪掉。
