Customizable Salon-Smooth Results That Last for Months
I’ve used the Let Me Be Hair Keratin Treatment twice, with a 4-month gap between applications, and I’m very impressed with the results. The first time, I left it on my hair for 1 hour, and the result was a very sleek, ultra-straight, frizz-free finish with intense shine—definitely a strong, salon-level smoothing effect. While I loved the results, I realized I wanted something a bit more natural for everyday wear. For the second application, done four months later, I left it on for only 30 minutes, and this gave me exactly what I was looking for: smooth, frizz-free hair with movement, softness, and shine, without looking overly flat or stiff. Another big plus is that my hair did not become dry over time, even months after using the treatment, which is very important to me when it comes to any smoothing or keratin product. The application process is simple and straightforward. I washed my hair with a regular shampoo, applied the product, let it process for 30 minutes, rinsed only, and then finished with a blow-dry and flat iron. Easy to do at home and very effective. ✨ Pros: • Customizable results depending on processing time • Excellent frizz reduction • Soft, shiny, and hydrated hair • No dryness even months later • Easy application and great yield ⚠️ Cons: • The smell bothered me a bit on the first day after application • Since I color my hair, I noticed some color fading - the video I posted clearly shows how much my hair color faded after using this product Overall, this is a very effective keratin treatment that delivers professional-looking results and long-lasting smoothness. I highly recommend it for anyone looking to reduce frizz, boost shine, and achieve smoother hair with control over the final result.

Really works
Works amazingly well. My hair has never been so sleek and poof-free. Does make your hair smell though. The odor reminds me of urine after eating asparagus. Be forewarned.

Easy to apply, great results
I put pictures because I think they can tell more. The first one is how my hair was before(6 months not straightening) . The second one is after the process ( I left the product on my hair for 90 minutes, rinsed everything of, then dried, then iron flat each little part 20 times and wash again the next day). The video is how the back part is after natural dry( I didn’t use anything). The last one is my favorite, it is also how it looks with natural dry but the front part. My opinion: its a great product, I know the back is not all straight like you can see(thats why I didn’t give 5 stars), but the front came out very straight. I also consider that i did it by myself(I use to do it with others straighteners too). I’ll do it again in 3 months and see if I can get the whole things straight, anyways I liked the result, it takes me 2 minutes to get my hair done now.

No results
This did nothing for my daughter's hair. We left it on 1.5 hrs. She has virgin healthy hair and her hair is way less curly than the model on the picture.
