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.

Good for the price
I wanted to share an honest, real review for those who want to buy the product. I bought it because i saw many reviews here and on youtube that claim to go from a really curly (even afro type of hair) to a shiny straight one. I can’t talk for everyone since we all have different types of hair but i came from a wavy, frizzy hair to a less frizzy and more shiny but still wavy hair. I would like to add that i use shampoo and conditioner that are specifically for keratin treated hair and i don’t use any other products. I do like the results basically because i like my waves and my main issue was the frizz and even though i still have a little bit of it it looks much better than before. That’s it folks hope it helps!

Easy application and great results
This product is really easy to apply and the results are great. My hair is wavy but frizzy and after I apply the product frizz disappeared, left my hair shiny and soft, doesn’t feel heavy on your hair. I’m going to be able to reapply the product, two application with only one bottle.

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.

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.

Does what it says
Don't expect miracle but product does what it says. I have very tick, frizzy and dry hair and in the past I tried everything, keratin treatment, all kinds of shampoos and hair masks, serums and oils and nothing really ever solved my problem. My problem is that it takes so long to wash hair, dry, style it, and still it looks frizzy and unmanageable. This product made process less painful as it does smooth hair, it does eliminate some frizz and it's easier to style the hair. I am happy that I bought it
