Good product for fine hair
The smell is a bit bothersome because it doesn't leave your hair. But the result is as expected. I recommend it for fine hair; I don't think it's good for thick hair.

Amazing Treatment for Pregnan and Breastfeeding Mom
Love it🥰 My hair changed immediately and I didn't used iron comb nor could do the application at the same moment which proofs the quality of this product. Also it has no smell at all and it is not alergenic. Regardless if you have a baby around the blower and iron do it outside the central AC just as a precaution.

Feels soft.
I love my hair feels after the treatment. I can blow dry my hair in less time. I am blonde and this products lightens my hair so after the treatment I like to put an ash blonde to bring it down. Love it.

This hair treatment leaves hair softer, smoother, and more manageable. It helps repair damage, reduce frizz, and add shine without feeling heavy. Great results after just a few uses and ideal for dry or treated hair.

Worth the price
I’m in love with this product. The shine this product leaves in your hair is amazing. I have my hair to my waist, I use half of the product and still have another half for the next touch up which I do it 2 or 3 months apart. I gotta say it has helped my hair out so much. I now have more volume, shine, thicker hair and less frizz. Make sure you leave it in for 45 mins before washing it off. Once you rinse it off it will have some texture to it left behind; no worries it comes off within the next wash. I absolutely love this product.

Maravilloso. Me he hecho muchos tipos de alisados y puedo decir que este producto es una maravilla. Pros: el proceso es muuuucho más sencillo al no tener que secar y planchar el pelo con el producto puesto. Huele muy bien y apenas saca humo al pasar la plancha (con los otros alisados me escocían los ojos y la garganta) Deja el pelo suelto, sedoso y con brillo, que ya se nota sólo al secar con secador. El bote lleva bastante producto como para hacerlo un par de veces (sale rentable). De momento, no le veo ningún pero. Sólo me falta ver cuánto dura el efecto, pero al menos, me ha dejado un aspecto y un tacto increíble.

✨ Resultado (en mi caso) Lo uso junto con el champú de mantenimiento de la misma línea y estoy muy contenta: el pelo queda más liso, brillante y con menos encrespamiento, y el efecto del tratamiento me dura bastante tiempo. De hecho, yo lo hago cada 6 meses y el pelo llega tan bien que podría aguantar más. 🧴 Para qué está pensado Es un tratamiento de alisado “express” orientado a dejar el cabello liso/suave y sin frizz y, según la info comercial, el acabado puede durar más de 3 meses (dependiendo del cabello y cuidados). 🛠️ Aplicación (importante seguir pasos) En varias fichas de producto se indica aplicación con el cabello seco, dejar actuar aprox. 40 min (según tipo de pelo), aclarar, secar y planchar en mechones finos varias pasadas.
