Rejuvenol 24 hours Keratin Treatment with Collagen - 2 oz

Have purchased several times and works just as well as when I first purchased.Lease hair smooth and sleek. Easy to applied and you save a lot of $$ compare to salon prices.Definitely use in a well ventilated area or wear a mask.

I use this in between my once a year deep keratin treatments. I use a clarifying shampoo and then spray this on after I dry my hair. Then dry it again and use the flat iron. It lasts about 3-4 weeks. Leaves my hair nice and smooth and has a pleasant smell. I've used this product for about 10 years. My hair is naturally wavey but the humidity makes it fuzzy, that's why I use this.

If you have thin hair and don’t need to pay for expensive keratin/Brazilian treatment….. then this product is for you. It works great. I suggest having someone help you flat iron your hair to make sure you get close to the scalp. Absolutely love it for $12

After reading the instruction I decided to return. You need gloves, mask, well ventilated area and it can’t touch your skin.

I love this product! I've been using it for a long time. I have shoulder length, thick, course hair and this leaves my hair silky and soft. I don't use the clarifying shampoo. Instead I use L'Oréal shampoos that don't contain sulfate. I skip the conditioner the first time I apply the keratin. The little bottle is more than enough for all my hair. I use the rest for touch ups here and there.The down side to this is that once you start applying heat is smells really bad and burns your eyes. Always use gloves and a metal comb. This product will burn through plastic combs. Make sure you're in a well ventilated area.I've attached a picture :)

My salon used this on me and charged over $300. I quickly paid attention to the product when it was being applie. This way I was able to buy it online for $20 and did the touch up to myself months later. I did an even better job (because I did it to my taste) and I was able to CONTROL where the spray went. At the salon (Y Gallery in NYC, please AVOID this place is awful!) they sprayed it right on my scalp which the product explicitly states against. When doing it myself, I did not feel my hair was damaged afterwards, and I did and still do notice a difference in better shine and texture. But while using the application I did develop a headache, burning eyes, and nose. However, not nearly as bad as the other products, but still has the chemicals that are not good for you (I don't think there is a way around this in our current time). I strongly suggest doing this outdoors or in a very well ventilated area because the chemicals are definitely not good for you. I sprayed it one inch from my scalp, used the blower to blow it out straight, and then a hair straightener to "seal" it in, as the salon did. At night I kept my hair in a shower cap wrapped up so I wouldn't sleep on my hair (reduce skin exposure to the chemicals).

I do this product myself once a year. I like silky shiny hair. It's easy to use inexpensive and get the same results as paying $250.00 and up. I would advise however to open a window when you use it. It does have an oder. Great product!

This is a handy, diy, inexpensive alternative to a salon keratin treatment. Those treatments last about 3 months, this one more like 4-6 weeks and even initially you don't get that same super sleek silky feeling like you do from the salon. Also the fumes are pretty bad (watering, stinging eyes), so be sure to do it in a well ventilated area. BTW, my hair is fine (but there's lots of it) and wavy, so I use this for sleek, easy to blue dry hair. This only marginally helps.
