Not sure
Sampled

I like the smell of this product, however, I am not sure the impact on my hair. I think the sample was too small to tell

Did not like the scent
Purchased

This product was effective enough as a serum, but it smelled (to me) a lot like piña colada. If the scent of a product is off-putting to me, I won't use it, no matter how effective it is. Unfortunately, this is one of those products.

The best!
SampledPurchased

great to use on damp hair or after straightening to calm down any frizzy hair. Smells great and has lasted me a while although I am finally about to run out!! Time to get a refill.

Nice hair serum
Sampled

I used this before blowing my hair out when it was a little damp and my hair came out smooth and silky. I used up the sample very quickly because i really like the texture and scent. I would purchase this in the future when I run out of my current products. I think this is a good product for people who have a lot of grey and they are color treated so the hairs smooth better.

Loved It!
Purchased

I'm not sure if it will help with hair breakage yet, but I love what it does to my hair and I do think my hair is looking better already. This product is light weight and smells great (but not over powering). A little of this elixir goes a long way making the price not so bad since one bottle will last quite a while!

Great scent
SampledPurchased

This Elixir makes my hair smell great! Its repairing qualities are questionable, but it definitely made my hair softer and easier to style.

Awesome product!
Sampled

This Rejuvenating Elixir is probably one of my most favorite samples I have received from Birchbox. I use it very often and it works so well. Once I ran out of my sample, I purchased a large bottle and I love it. Not only it works well on my hair and make it very smooth, it also smells great!

Smells great but pricey
Purchased

Smells great. Used even later in the day as a touch up, but too pricey to re-order. It was a little hard to apply with the dropper, a spray would have been better.

Youth Renewal Elixir
Purchased

I rec'd these as a sample in my Birchbox and really liked it enough to purchase. We are always thinking of keeping the youth of our skin. I love the idea of keeping our hair youthful too.

Compliments on my hair since I started using this product
Purchased

I received compliments from coworkers and friends alike a week or two after I started using this product. It smells great, goes on smoothly, and improved the texture of my hair. My hair has been shinier and smoother since I started using this product.
