Ayuda a matizar el color y Review: Frizz free - I received my package a little earlier than they said it would come. I let my stylist do the treatment for me because I didn’t want to do it myself. It’s been almost three days my hair is still straight and shiny even though it has been raining here. The humidity did not make it frizzy. I will see if it still holds up after I wash it. So far so good. Review: Great product - Perfect on my client's 4c ha6. Last her at least 5 months before her curl pattern began to fully come back ## Features - smoothing hair treatment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08K5P4NT8 | | ASIN | B08K5P4NT8 | | Best Sellers Rank | #284,830 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #498 in Deep Hair Conditioners | | Brand Name | GEMS STYLE | | Customer Reviews | 5.0 5.0 out of 5 stars (5) | | Hair Type | fine, All | | Item Form | Cream | | Manufacturer | HODM | | Manufacturer | HODM | | Material Features | Plant-Based | | Product Benefits | Strengthens hair roots and protects from environmental damage | | Scent Name | Lavender and Rose | | Special Ingredients | cysteine, formaldehyde-free, argan oil, macadamia seed oil | | UPC | 608374886321 | | UPC | 608374886321 | | Unit Count | 1.00 Fluid Ounces | ## Product Details - **Brand:** GEMS STYLE - **Hair Type:** fine, All - **Item Form:** Cream - **Product Benefits:** Strengthens hair roots and protects from environmental damage - **Scent:** Lavender and Rose ## Images ![GEMS STYLE Cysteine Hair Treatment Formaldehyde Free For Blonde Hair 9fl.oz - Image 1](https://m.media-amazon.com/images/I/61Qu2H8sr-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Frizz free *by C***N on January 23, 2026* I received my package a little earlier than they said it would come.
