The Ultimate Humidity Shield for Frizzy Hair
If you struggle with rough, unmanageable hair, this serum is a must-have. The avocado and grape-seed oils deeply hydrate my hair without making it look flat or greasy. It lives up to the 72-hour frizz control claim and easily tames my flyaways, even on humid days. I love that it’s completely paraben-free and has a very light, non-sticky texture. It instantly detangles my hair after a shower and leaves a brilliant shine.

Nice and lightweight, but results are ordinary
I like that this serum features avocado and grape seed oil without feeling heavy or sticky. It leaves a nice initial shine and makes combing through damp hair easier. That said, the effects wear off pretty quickly in humid conditions. It’s a standard, middle-of-the-road serum that does an alright job, but nothing extraordinary.

Finally, a product that works!
Wow! I have spent an absolute fortune on products that claim to smooth my menopause dry hair, 100% of them failed...until now, I love it, a little goes a long way, leaves my hair soft and shiny without leaving it unmanageable, I have fine hair but a lot of it and I will be stocking up on this!
