Review: Formaldehyde free, easy to use, great result at home - This is amazing product. It is easy to use, results are 100 straight silky, shine and soft hair. I have afro hair, and worked perfect. The best thing! It is Formaldehyde free, it does not smell awful like usual keratin treatment I have had in salon. Review: Good value for money and certainly worth a try - Came on time, and is easy to use. A bit of an odd smell, but worth it (would recommend as many windows open as possible!) but doesn’t have that overwhelming irritating stink of formaldehyde. I’ve 3a hair type and whilst it did have a positive effect I think 3 months would be more than long enough interval - not like what was in the description which I think said 3 months was minimum - but it does depend on hair type/washing frequency I guess! The main appeal for me was the low price compared to the salon cost, the volume is definitely generous and takes a couple of hours max (I used the shorter curl keeping method) and the savings when you’re on a budget makes it worth a try for sure! The instructions included were well written as well. ## Features - Inverto 60 is made with Advanced Penetrating Gel For Faster Better Results.

A bit of an odd smell, but worth it (would recommend as many windows open as possible!) but doesn’t have that overwhelming irritating stink of formaldehyde.

The instructions included were well written as well. ### ⭐⭐⭐⭐⭐ One bottle is enough for 1 treatment on very long hair *by T***S on 19 July 2020* Very good product. I have extremely long hair (easily cover my breasts) and the whole bottle was barely enough to cover my hair, I had to brush it a lot to cover the tips and it was very painful! I washed the hair the next day cause I was afraid it didn't work ahahha Next time I will buy 2 and use 1 and a half each time. It works perfectly if your hair is not very curly but frizzy, as mine is. The discoloration is real though, but I don't mind as the color it gave me is quite nice anyway! In the photos you can see the before, after and after the iron. Very shiny and soft, it closed all my split ends( my hair was very damaged, I had to keep it tied up all the time to avoid crying while brushing the day after :() Smells a bit funny and it smokes quite a bit when you are straightening the hair, but nothing too crazy. Will buy again for sure! ## Frequently Bought Together - INVERTO 60 Multi-Functional Keratin Hair Treatment Formaldehyde Free Super Fast Application Process includes Starter Keratin Treatment kit Results are Instant delivering healthy Shiny Beautiful hair - Keratin Shampoo Set For Frizzy Damaged And Color Treated hair INVERTO SILK Luxurious Sulfate Free Shampoo and Conditioner Two Bottles Value Set 2 x 360ml Protect Hair Color Eliminate Frizz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/85636124-inverto-60-multi-functional-keratin-hair-treatment-formaldehyde-free-starter](https://www.desertcart.tn/products/85636124-inverto-60-multi-functional-keratin-hair-treatment-formaldehyde-free-starter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-17*
