Gussi Reviews

Used their product and followed through on instructions, sadly it did not live up to its expectations. After one day, my hair went back to its original state. No transformation in the slightest.


The company needs to behave with integrity and look for ways to improve their product instead of deleting bad reviews on their platform.

Has no effect 🤷

I have done keratin treatments for 10 years every summer and swear by them as my summer beauty secret. I was thrilled when his product came out- but also wary. I wasn't convinced I could do it myself and that a natural product would have great results. BUT- after my application I was thrilled with the results. I have medium/thin hair that is really prone to humidity related frizzy and random curls. The gussi system gave me the salon quality sleek hair and waves that I love for a fraction of the price. Given my medium hair length- I only used half the bottle and have another treatment to do- but my treatment lasted 5 weeks well- probably an additional 4 weeks with some impact. Pic attached from a week later with a quick blow-dry in Florida humidity! I would give a 7.5/10 compared to a salon treatment- but the price and convenience and covid-safety make it all a 5 ranking!


Takes longer than I expected- I tried to squeeze in doing a treatment in the evening and made everyone late to dinner. Suggest giving yourself at least an hour- and honestly could be helpful to have a friend as an assistant.
