Birchbox Breakdown

Leave it to the whizzes at Living Proof to help you earn your PhD—perfect hair day, that is. This nourishing conditioner is made with OFPMA, a patented molecule that keeps hair cleaner for longer, so you can rock your blowout an extra day (or two). The innovative formula also smooths and strengthens hair, detangles, adds volume, and gives you a polished style—and it doesn’t get more perfect than all that. What’s more, this formula works on all hair types, including color- or chemically-treated hair, and protects hair against UV rays and heat styling. It’s made without sulfates, silicone, or oil.

Worth the money!
Purchased

I was a little skeptical of the product, based only on the price. However, I've been using the 5 in 1 product for a while now and love it. With a coupon code in hand I ordered the shampoo/conditioner set. I am pleasantly surprised, the product does exactly as advertised. I am currently on day 4 post wash and my hair is still doing great with just a quick flat iron touch up in the morning. It feels clean, soft and light. The only thing I hate is the bottle! It is not easy to get the product out, I really have to shake it and squeeze hard. Definitely a repeat buy in the future!

Love it.

I use this in conjunction with the PhD shampoo, 5-in-1, and Night Cap, along with the Full Thickening Cream. My hair has never looked or felt healthier, or taken less time to style. I have fine, wavy hair (and lots of it), and this helps it to stay hydrated and frizz-free without weighing it down. Definitely a keeper.

Good conditioner
Purchased

I use this in conjunction with the shampoo and it's given my fine hair more texture and body than any other product(s) I've tried in the past. It moisturizes my hair without weighing it down. I highly recommend this conditions (and the shampoo).
