keratin hair fibers for thin hair & hair loss | 50g | instantly hair thickening powder | made of natural keratin (1.76oz black)

¡No suelo escribir reseñas, pero tuve que hacerlo para este producto!Esto funcionó de maravilla conmigo con una cobertura total 10 veces más gruesa y con un cabello más completo, probé otras marcas de fibras capilares. Encuentro que esta se ve más natural y menos desordenada y el color combina perfectamente con el color de mi cabello que nadie puede ni siquiera. Dile que tengo fibras espesantes para el cabello. Muy recomendable.

Totalmente satisfecho, el producto se adhiere muy bien y sobre todo cubre esas partes no muy pobladas de manera excelente.

Seemed like just colored powder, without any fiber. Did not cover well and did not make my hair look thicker. I can see why this product is so cheap. Toppik brand is much better. Also, the light brown color looks more like dark red. I am going back to Toppik.

Reasons for 3 star rating:Under Product Page, bullet point #4 - "Easy to Use -and remove - shake in the fiber powder onto the thinning area and gently pat down - To remove just wash the hair with shampoo."I tested it with my hand since I can't see on top of my head. Shake the bottle and pour some fiber powder onto my hand. Gently pat down and the powder scattered everywhere. A few minutes later, found no trace of the powder, even I have not wash it at all. Did not mark this product all the way down because on the box, it states, "Fit the fibers with hair spray".This will be a little messy as the powder does get down from the hair before hair spray can be applied. Unless someone is doing the job for you (like in their video). Otherwise, with our movement to get things done, there will be powder on the shoulder/ground. Depending on how much powder was used, the mess may or may not be totally obvious.Other than the above observation, this product does help to volumize hair condition. I do use other similar products that do not require hair spray. Thus, I feel this is an average (3-star rating) product.

I like how it covers the thin spot in my scalp. Learned to use with a "light" hand so that it doesn't pile up on natural hair and look unnatural.

1- The quality of this Brand is amazing، from the time you use it you will find out this is the one2- quantity of this brand is lot compared to other brands3- customer service is the best with the fastest shipping ever

I saw this on TikTok so I decided to try it, I’ve been using hair fibers for the past Couple years I’ve tried different brands, I find this worked the best with me, I’ll definitely Switch to OPTRk,

I’ve used a similar product and thought Id try this brand. While it seems somewhat effective at thickening, the application is so messy i cant recommend it. Every time I used it my bathroom was coated with a layer of powder. The holes are so small you have to shake it and there are so many holes its impossible to control where the powder goes. Super messy.
