It is easy to apply, it doesn't have a bad smell, I loved the softness and shine it left in my hair

I’m going to give you the breakdown of how to use this for relaxed African American hair.First of all the reviews that talk about it burning are correct but it’s not a relaxer chemical burn it’s more of a burning sensation. EVERYONE who uses this product should be instructed to baste the scalp with a petroleum based product so that the product does not touch the scalp. Once air hits the product it activates this “burning” sensation even more so the scalp cannot be in contact with the product.Secondly, I used a plastic cap to mitigate drying of the product because it is not supposed to dry on the hair. If you leave it exposed to air for 45 mins then the likelihood of it drying is greater so either cover it with a plastic cap OR make sure you have enough product to constantly apply.You must shampoo the product several times in order to get it all out. If you experience clumping of the hair, just detangle with your fingers when the shampoo is in and use the conditioner liberally after shampooing.You have to use a leave in conditioner and argan oil of some type to continue the conditioning of the hair through styling. In short I only left it on for the minimum amount of time 20-25 mins and there was not significant straightening or relaxing of the curl patter at the root however my hair felt super strong and I have almost no breakage or shedding in the styling process. Overall I like the product and will use it again with these points in mind and leave it in for 45 mins to see what happens.

Size es demasiado pequeño para el precio tan alto. Pense el tarro era grande. Y al usarlo tan cual lo muestran, no funciona, me lo dejó súper seco, sin brillo, luché mucho para alisarlo. La verdad no lo recomiendo ! Lo dejé 45 minutos en el cabello seco, luego lo lave con abundante agua, volví a secarlo y plancharlo, que quedó con freezing y muy seco ! Muy triste creo que bote el dinero

This treatment is super easy to apply at home—no professional help needed. After using it, my hair felt incredibly soft and smooth. It effectively controls frizz and gives a healthy, shiny look. I’m really happy with the results!

I recently tried the Liss Expert Stem Cells Smoothing Treatment, and I’m genuinely impressed. My hair feels incredibly soft, smooth, and manageable. The application process was straightforward—apply, wait, rinse, and flat iron. After using it, my hair looked shiny and frizz-free for weeks.I love that it doesn’t contain formaldehyde, so I didn’t experience any strong chemical smells or irritation. This is definitely a salon-quality treatment I can use at home. Highly recommend it if you want silky, straight hair without the harsh chemicals.

Tuve muy buenos resultados utilizando el producto, espero que cuando lo utilice una segunda vez la mejoría en mi cabello dañado por la decoloración sea aun más notoria.

I tried the LISPERT hair treatment on the recommendation of a friend and I am delighted with the results. My hair is naturally frizzy and difficult to manage, but after using this treatment, it was noticeably softer, smoother and shinier.The product has a creamy texture that is easy to apply and a very pleasant aroma. I followed the step-by-step instructions (washing, application, drying and ironing), and although the process takes some time, it's really worth it. I noticed a big difference from the first application.
