I purchased the full soze tube of this after reading reviews on Birchbox. I never received a sample of it, but out of everything I ordered that day during "Sweet 16", this is a winner.
I have exceptionally dry, fine, color-treeated/damaged hair that can stand up straight in front from breakage. I've tried many prestige-brand oils and creams and found they either did nothing, made my hair dull, flat or felt heavy. I also find I'm allergic to many brands.
This has been a delightful find as it not only smells wonderful, no allergies, no heaviness, makes my hair shiny and easier to blow dry and keeps the flyaways tamed for the most part.
My only caution would be to start with less than a dime-sized amount and build from there. I used more the first time and my hair was a bit flat. Next shampoo I used much less, dried it and used a bit more on my flyaways before flat ironing. That worked wonders. For the price, the tuvbe is large and so small an amount used that it's worth it.
As someone trying to survive breast cancer who still works, I wish they'd make a travel size as I'm on the go a lot.
This and Miss Jesse's Super Slip Sudsy Shampoo, which completely detangled my long hair have replaced almost all other hair products.
The other two products I ordered, Miss Jesse's Rapid Recovery Treatment (way too heavy for my hair texture leaving it looking dull and not nourished) and Bain de Terre Blow Dry Smoothing Cream (smelled heavenly, but didn't do anything and made my eye's red and watery) were not hits.
I wish Birchbox would send samples on request to subscribers or a twice-a-year "design your own box" of 5 samples so many of us could try what we've been thinking about before purchase.
Sidenote: hair and skin change radically over the decades. It would be wonderful if Birchbox would take note of that. I'm in my later 50's, look much younger, not into green nail polishes, bright reds on my lips or fads and work in a high stress field where this stuff is a definite "no". I'm also medium-skinned, but it's translucent with pink undertones. Most boxes end up with my daughter!
