Amazing results

I'm really glad I decided to purchase this product even after reading the reviews about the terrible stench. I'm not gonna lie, the smell is pretty brutal and it did sting my eyes while I was applying it (so please do try to do this in a well ventilated area). But if you are able to get past the smell and deal with it for those 3-4 hours process, then it is well worth it! Although the instructions say you can rinse the product off after 30 mins to an hour, I decided to leave mine in overnight and washed it out the next morning and BOY, my hair was silky smooth and so shiny! I have a ton of little fly-away baby hairs and I made sure to apply more product to these areas but even my fly-aways were laid to the gods!My hair falls right above my bum and I knew if I were to get it done at a salon, it would easily have been around 400$ so compared to salon costs, I think that this. product is totally a steal for the amazing results. Again, if you are sensitive to smell -- I would recommend you opt for a formaldehyde-free product, but if you are able to able to deal with it, you won't regret purchasing this :)

This works!

Wow. This works! Since Ive done the treatment, all I do is get the excess water out of my hair with a towel and then let it air dry and it is almost perfect! And for the products. The actually treatment makes your eyes water, but after that its fine.

good product to DIY at home

i like the coconut burns your eyes, i even wore safety glasses while doing my own hair, but it still hurts,recommend you do it in a larger well ventilated room ..but i think that's normal for all chemical products.. even hair dye burnsthe product I would say lasted for about 2 weeks? i was hoping it was permanently straighten it longer, but after a few washes my hair was wavy again. I wonder if I didnt use a curling iron that was hot enough? mine only went up to 425..I also followed all the steps exactly and took me 3-4 hours total!I will try it again and see how the second times goes

Best by far! Will buy again!

Amazing.. love love.. used this exactly a week ago.. made my hair so soft! I did this myself with double mirror for the back of my head.. I'm impressed.. make sure you use a flat iron that goes to the 400+ degree heat setting. Also very strong while putting in hair.. so use a fan to blow away from your face as your eyes will burn.. n open a window if you have one in the bathroom n use the exhaust fan in the bathroom also! Anyway hands down best results and easy easy to do.. Love that it didn't take that long.n regards to the steps. plus... After rinse it's not an awful smell.. I did wait the three days that all others recommend but this does say after 3 hours it's ok.
