Review: 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.
Review: Amazing Results on 4B Hair! - I have 4B hair, and this treatment worked amazingly! My hair was very frizzy and tangled before, but now it’s smooth, soft, and easy to manage. I used it to temporarily straighten my hair with the RevAir and a flat iron because I wanted sleek results without losing my curl pattern and it delivered. My hair has never been this straight, shiny, or smooth when I’ve done it myself. I’m beyond happy with how healthy and manageable it feels! The steps I used: 1. Washed my hair with a clarifying shampoo to get all of the product out of my hair. 2. Sectioned my hair, then applied the Let Me Be Hair Keratin Treatment. 3. Put a plastic cap on for about an hour. 4. Washed most of the product out, but left a bit in. 5. Applied a heat protectant spray. 6. Blow dried with my RevAir 7. Once completely dry, sealed the treatment with a flat iron. 8. Let rest for about an hour, then rinsed out with cool water and deep conditioned. 9. Rinsed deep conditioner with cool water and applied leave in conditioner to finish.
