Think your hair doesn’t grow fast enough? The real problem could be breakage, which is caused by heat styling, overbrushing, and even aging. Give your strands back their youthful luster with this silky serum. It strengthens from the inside out, resulting in healthier, younger looking hair in just one week.
I use this every day before I style my hair and I can tell it's less frizzy. Smells amazing, too!5
Used this one time, and what a difference. Hair is smoother and shinier already. I may be adding more product to my morning routine.5
My hair has been really damaged over the years from heat, and color and the like. This product though helped my hair feel so healthy and smooth! I used it up really quickly, if I had more money at the moment I would definitely buy this in a heart beat!4
My hair definitely felt softer and smelled great after using this. Not sure if it actually strengthens your hair but its a nice product.4
My hair is dry and over processed and this really ands a nice shine and softness to it. It adds moisture without weighting down my hair.5
I didn't notice any affects from this product one way or another. Perhaps longer, heat-styled or more damaged hair might experience some benefit. It smelled nice, though.2
The only way to describe my feelings for this product is - OBSESSED!!! I've bought (2) full-size bottles since my sample arrived in April. It has changed the life of my hair! My dry hair is now soft and manageable! It's a life saver!5
I LOVE this product
I bought the full size when I saw it at a local store
I was intending to buy it but the price was great
My hair has grown so much since using this and has more shine
This is a must buy!
I definitely saw the change in my hair after a few trials. I loved the way it made my hair feel, as far as my damaged ends but i do not think it made my hair grow faster by any means so that's why i gave it 4 stars4
This is the first product that I have received from my year and a half with Birchbox that has inspired me to write a review. It turns out that for my fine but thick hair, this product is the secret to good hair days. I am truly astounded at the power of this serum to keep my wavy, and occasionally frizzy smooth and full of body all day, especially as you only have to use three to four tiny drops on damp hair before blowing it dry. I'm very glad to have found this product.5
