it was a horrible experience to get my hair done there. first of all, I chose coloring treatment, with existing processed hair condition (I pointed it out ofc) and the colourist seemed to only know the very basic knowledge of hair colouring, not even the whole science behind it. when I asked for an underlayer, the colourist looked a bit confused so I gave him a photo (underlayer is a juicy trend now. come on...) when I bleached my hair, my hair wasn't covered at all, either using foil or haircap... when I asked, it's even said that it's not necessary because this is not a highlight/balayage. Maybe it's thought that the function of the foil strip is only for blocking hair sectioning, even though the developer = hydrogen peroxide = reacts to heat and heat from closed hair = opens the hair cuticle for better penetration, of course it helps speed up the whole process. .. just like when I dyed it, my hair was dyed wet, then it wasn't covered... I asked if I didn't dry it first, instead I said that l*r*al products can be used on wet hair. even though the point is not that, hair dye application on wet hair is possible for certain situations, such as to achieve subtle dimensions but will not "lift" the vibrancy. imagine when the developer is cool down and does not process optimally for pigment absorption because it is not covered, causing the results to be super patchy and not saturated. then it gave me the impression that I gaslighted because of the condition of processed hair and because I chose "that one" color. I've been in and out of hairsalons for years, this is the first time I've really experienced such widespread bleaching & haircolouring. incredibly speechless and I'm sorry, I'm not kidding. considering I've used cool tones a few times like ash grey, ash lavender, dark blue, bluemoon (the color is almost the same as the one I chose at HC GI) with exactly the same hair condition, the result was sooo much better when I got it done in other places. the point is to pay expensive but zonk, better fix it elsewhere.
