John Yim haircoat review, with PICS!!!

I did a take down about a week ago and decided to try John Yim haircoat one more time. The hair I used it on is about 11 weeks old, I’d say.
I gave this install hair a few good clarifying shampoo, I used the Neutrogena anti-residu one, it is pretty good I think.
Moreover, I decided to try the haircoat on a few bundles of hair pieces I had, most of it is old hair, I had to brush it to get rid of the tangles, so it sort of increased the puffy frizzy look of these wefts.
This is the hair that you on the floor pictures.
I actually was concerned that the results wouldn’t show so well on picture, sometimes the difference in shine and texture can he hard to tell through pictures, but I think you’ll be able to tell the difference. :roll:
I used about 9ml of hair coat (6ml of the silky formula, 2ml of the formula for damaged hair and 1ml of the shine formula) in 500ml of water at the required 45 celsius temperature.
I controlled the temperature of the water first, measured the 9ml with a syringe and poured it in the warm water.
I treated about … I’d say 15 ounces of hair with that. You could probably do more. :mrgreen:
It is important I think to have enough water to be able to really dip the hair and move it around in the mix. I could have worked with 400ml though, it would have been fine too.
This mix was 9ml of haircoat concentrate for 500ml, so almost 2%.
I think it was too much for my needs though and will probably go with 7ml for 500ml next time.
I dipped the hair for like 5-10 seconds, then took it out, squeezed out the excess liquid, then dipped it again for a few seconds, and that was pretty much it.
The results pictures are just the hair after being blow-dried thoroughly, I didn’t not use any conditioner or leave in products of some sort.

I really love this product, it is one of a kind, nothing compares to it. The silky smooth effect +shine do go away after about 14 shampoos I would say but, the hair remains globally much nicer than it would be if the haircoat treatment had not be performed. So in a way, it is a permanent improvement, only the most noticeable effects will fade away.
Basically, this install looks and feel younger that it should at this point, the hair that is more than 2 months old feels … not like 2 months old at all, it feels much much better. :Y:
I noticed that it improves the ‘waterproofing’ of the hair too. In humid weather, I usually have my bohyme going puffy and crazy on me, and this hair behaves a ton better now in case of rain. So it’s another big plus, and a permanent one.

Ok, one more observation I have made is that the mix will affect the first few wefts you will dip in much more than the ones that follow after.
So you want to use the most damaged/dry hair first when you use the haircoat, it still worked great on the last wefts, but there was less risk of greasiness afterwards. :vom:
Also, the most recent and in good shape your hair is, the less product you will need to use.
Almost 2% ratio is too much for me as I have found that some wefts –the first three weft, that were in not so bad shape- became sticky greasy. I had to clean them with clarifying shampoo and it wasn’t enough, so I tried liquid dishsoap, which did the trick.
The rest was perfect though.
You probably want to practice a bit to figure out on a small piece how much haircoat you need, which ratio works for which kind of hair etc.

Well, I think I am pretty much done with my “exposé”, hope you’ll enjoy my pictures!

 So this is how I got my haircoat concentrates directly from John Yim, the green formula is for damaged hair, the red formula is the silky hair formula -the best and most complete imo- and the yellow is for shine -my second fav!-

This is how the mix looks like (water + haircoat concentrate)

I plunde the thermometer in the water and make sure the temperature is 45 celsius -about 110 Fahrenheit I think- before I pour the haircoat into it

These are the two bundles of mostly old hair I had:

And the unfortunate greasy results :rolleyes: , that I was able to get rid of with dishsoap :

a little less greasy but still not great:

All this hair became perfect after a few washes
