Nanobeauty Brazilian Keratin Hair Straightening 150 ml Treatment Kit, Diamond Infused, Vegan, Blow Dry, Smoothing/Repair, Argan Oil, Professional Results

Frizzy hair before and smooth after, yes it stinks during the application, all normal. As expected, the hair color (tone) will slightly differ after the application (if your hair is colored). This is expected, and the difference is only slightly noticeable. I have highlights and a darker base, so now it's all a little ligher/golden tone, nothing that would make you run to the salon to fix, no. Would definitely recommend this!

I’m very impressed with this product, I’d go so far as to say it produces professional results. The process is straightforward, just wash the hair twice with the provided clarifying shampoo, towel dry and then blow dry. I applied the product with a brush, sectioning the hair. After leaving for 20 minutes I blow dried it straight and then used straighteners on high heat, straightening small sections. All in all from start to finish, the process took about two hours. Quite pleased with the results, I would buy again. The only downside is that the fumes given off during drying does sting the eyes, so be sure to have the room well ventilated.

I don’t usually leave reviews, but I have been so impressed with this I felt compelled to! I have very blonde, bleached hair which used to have a natural wave but is now more of a frizz and is very damaged, plus extensions. I was really scared to use this in case it caused damage, however it has been the complete opposite & a total game changer! It does smell very very strong upon application, however upon waking this morning my hair looks like I’ve stepped out of a salon - which for me is unheard of! Absolutely love this and cannot recommend enough - nothing has ever been able to tame my hair, especially overnight. Brilliant results

Hat für meine Haare nichts getan. Immernoch frizzy und trocken. Locken kommen nach einer Woche wieder

unfortunately wasnt enough for my whole hair (3b curls & puffy). would recommend 2 for curly or thick hair. Apart from that really good my hair is so much easier and less time consuming to straighten. cut my time from 1hr to like 30 mins & hair stays straight even in humidity. also feels sooo soft, and looks super shiny. the process isnt too long but it BURNS your nose and eyes when blowdrying/straightening it in so make sure to maybe do it outside or near windows. also my hair was very damaged from heat & bleach. and level 10 blonde but seems to have helped the condition i have attached a photo of my hair 2 days after straightening, still sleek and shiny which is rare for me
