Review: AMAZING! PLEASANTLY SURPRISED x 2 - UPDATED TO ADD PHOTO - this photo is a full MONTH after using the product. UPDATED *AGAIN* TO ADD PICS FROM THE 2nd TIME I DID THE TREATMENT - a year later! (Video and last pics are from 2/2024) I did get a haircut because I needed one, not due to any damage whatsoever. I have been going to a salon for my Brazilian Keratin hair straightening since 2009. I only need to get them done twice a year since I don't need to wash my hair every day. $450, twice a year, plus tip and driving equals a lot of money and time. I decided to try doing it on my own this time, because why not - I have seen it done so many times, and I could really use the cash in my pocket. Aside from not being able to cover my eyes like I always do in the salon, everything went true to form. I definitely needed better ventilation, it smells awful. I will do that next time. I am not making this up when I say this is just as good as the salon. For a minute I thought it might even be BETTER! I am definitely choosing this product from now on. If you have the basic knowledge of how to use a hair dryer and a flat iron there's no way you shouldn't be able to do this yourself. Just follow the directions. Don’t improvise. Also the hair mask and argon oil sample they give you in the package are AMAZING! Shampoo and conditioner are good but nothing different than others IMO.
Review: Great product - I have naturally curly hair but wear it straight the majority of the time and this cuts down on my drying time and having to flat iron. I normally have it done in the salon but wanted to try to do it at home. I Followed instructions on box, except I didn’t wash for two days and I didn’t use any rubber bands or clips and kept my hair straight as much as possible (not behind my ears or pushed back with sunglasses). Used the sample shampoo and conditioner and blow dried like normal, came out perfect, no need to flat iron and hair is so soft and smooth. Totally worth it if it last the 4-5 months like a salon treatment.
