Peter Coppola A-keratin Express Smoothing Treatment - Formaldehyde-free Formula for Straight, Voluminous or Curly Hair Effects Up to 1.5 Months

Very nice keratin treatment! I've had keratin treatments - professional and at-home - for close to 20 years with many brands. I've just done the second treatment (6 weeks apart) before writing this review. I love that this is a spray on and not the very time-consuming small sections of hair with a brush application. I have thick medium course, wavy-curly hair. Another plus+ is rinsing the product thoroughly rather than rinsing leaving a "slip", which can be difficult to judge, and if not correct effects the results. After the first treatment, and then shampoo a couple of days later, my hair felt smooth & silky and I could still add some curl and body. I have color treated hair and the color lifter slightly, but I liked the result of it. Other keratins can turn it brassy. The flat ironing also can lift some color when doing these treatments. I walked in the rain from a parking lot into a store to test - and no frizz! I'll continue to use this product; I have found it to be one of the best for my hair. Here are the instructions I used and how to open the spray bottle, which is not obvious. To open the bottle, look for a square shape and push it in. To close push, it the other way. It's a bit hard to see at first. 1. Prepare the hair - Ensure hair is freshly washed and dried before application (blow-dry to smooth). 2. Shake the bottle well before use. 3. Apply the product evenly to sections of dry hair, avoiding the roots. (I comb through the saturated sections). 4. Wait and leave the product on for 20-40 minutes depending on hair type. 5. Rinse thoroughly, then blow-dry and straighten hair. 6. Wait 24-48 hours before washing hair. Tip - after finishing the entire process I use one-pump of Moroccan oil starting at the ends working it in up to the mid-section and then smoothing the top with any left on hands. A professional did this once and it made a great difference in the softness and helping with any drying from the process.

Amazing keratin treatment, very gentle! I still have my curls when wet, but they are so much easier to manage. I have 4a/4b curls and this bottle will last me a while. I didn’t even use half for my first treatments. I watched MANY keratin treatment videos before I did the treatment; so I felt confident going in. Barely any smell, and easy to use.

The product worked great on my hair (so far), but the packaging is ridiculous! The squirt bottle was cheaply made and impossible to open, so I couldn't spray it on hair at all! I was afraid of breaking the platstic handle so I had to pour it into another spray bottle I had to water plants; luckily that worked.

Great product. Works well. Last 4-5 weeks. Relaxes & straightens hair

Not frizz, and hair is smooth.

I am a little confused with this product. The packaging was horrible. The bottle was slightly open already and product was everywhere. So after I got the mess cleaned up, which was annoying, the bottle itself did spray and work as normal so it was easy to use. However, I don’t think this is really worth the cost. I could maybe see slightly less frizz and my hair did feel smooth but I am a little skeptical! The bottle says for professional use only, so that makes me nervous as I am definitely not a professional.

Small bottle - I had a hard time trying to get the sprayer to work - had to take it off completely, then put it back on facing opposite. Liquid is not too thick - fairly watery. Once you apply it to damp hair, just dry as normal. No scent to it, very easy to apply. Helps with smoothing out frizzy hair. What I didn't really like about the feel of my hair with this treatmet, it feels abit more weighted. My hair felt like it had some residual tackiness overall. I prefer a more light and clean feelig hair, so this product isn't to my liking. Not sure if it absorbed over time - indicates it lasts for a month. I've washed my hair since applying it, and the hair feel is more to my liking now. But I'm sure the product has its benefits, the feeling is not to my liking. Overall tho, is very easy to apply.

Product did not quite worked as I expected it. Did not take away much of the frizz, I have some left over, will try again and see.
