8 months ago I had a keratin treatment, no formaldehyde, and it left my hair smooth and shiny, but much less body than it had before. It looked really pretty, even though my hair is fine. My current salon only uses agave, so I decided to give it a try. It was the same price as the keratin, $150. After the treatment, I had to leave it in my hair until the next day, which was the first problem. My hair was flat on my head and it also had the color bleached out leaving it looking and feeling disgusting. Instead of light brown with blond highlights, it turned brassy strawberry blond, awful with my skin coloring.
The next morning, I couldn't wait to wash it out. My hair had NO body and can't hold a curl from a curling iron for more than 2-3 hours. My color had to be corrected and new highlights added over the next 2 months at an additional cost. It still has no body or wave and I hate it. Don't ever do this process unless you want to ruin your hair. I may do keratin in another year, but never agave!

Had an agave treatment done at a salon last week to relax the wave of my hair, and hope for less styling time.

Pros: My hair is shiny, and takes less time to blow dry to style.

Cons: THIS PRODUCT REEKS - REEKS REEKS when wet. Dry, the smell is not as nauseating. When damp or wet you will pray you are alone to spare yourself the embarrassment. My towels are holding the awful smell (praying borax helps), my family avoids me after showering until I've dried my hair. I can't bring myself to use the shampoo/conditioner that came with the treatment, it's the same awful smell. My colour is visibly lighter (?) and a cut after treatment was required.

In combination with the terrible odour, the in-salon expense makes this treatment a complete deal breaker. Its a very expensive time commitment both financially and time (approx 4 hours). Results will have to be long term and smell quickly fading if I were to ever consider this worth while. Fingers crossed in a few more washes the smell goes away.

I have fine super frizzy hair. Bottom line, it didn't work on my hair. It comes out smooth when I below dry it but it fizzes back up when hair comes in contact with moisture or if I sweat. Didn't work on me as I had hoped. My goal was to end up with a more relaxed curl and less frizzy. That did not happen. Less effective than regular keratine I have used in the past. On the positivie, it didn't irritate my eyes or made me cough when it was being applied to my hair. Also, didn't dry out my scalp like regular keratine does to me.

I did the agave oil straightener about a month ago now & regret doing so everyday due to this smell that's still in my hair. The effects of the straightener was gone after 2 weeks, however this awful stench has stayed. I've done baking soda, as well as a professional cleanse trying to get this smell out & yet it stays. It's ruined loads of laundry & stays in my towels, I don't go to bed with wet hair because of the embarrassing smell, not to mention its inability to wash out. I absolutely would not recommend it, it's been an awful nightmare. I forgot to mention that my hair is professionally colored & it stripped the color out. Ahhh don't recommend this to anyone!!
