Living proof.® Perfect hair Day™ (PhD) 5-in-1 Styling Treatment

By definition, a perfect hair day means getting a gorgeous ‘do without spending hours in front of the mirror. Luckily this multitasking styler does it all in one simple step, providing long-lasting volume and greater hair manageability with added softness and shine thanks to the brand’s patented haircare molecules, PBAE and OFPMA. It even blocks UV rays, safeguards color, protects against heat, and works over time to give you smoother, stronger hair. Plus, the formula is safe for all hair types, including color- or chemically-treated strands and it's made without sulfates, silicone, or oil.

Decent enough
Sampled

I like this brand a lot but this product specifically wasn’t that great. It’s also the 2nd time I’ve got it as a sample.

Pretty decent for my thin, fine, color treated hair
Sampled

I have very fine, thin, color treated hair with very dry ends. This does a very good job with everything except that the product I currently use also adds shine and this does not. That is minus one star, but it's good for everything else!

Another smoothing hair product
Sampled

I get way too much of this type of hair product. My hair is chemically treated with highlights and i do use heated appliances often so i am in great use of products such as this, BUT i have waayyy too many and would appreciate some other kinds of hair products to try.
I didn’t notice much assistance from this in smoothing out my hair strands either

I have a lot of hair, this was way too small.
Sampled

I have long, thick, wavy and healthy hair. This sample was not even almost enough for a sample test. No, I would not buy a full size just to try it properly. I have enough bottles of things that don't work laying around.

better than expected
Sampled

I didn't think this would work for my super fine, straight hair at all, but it wasn't bad. It did give me a little texture and volume, so definitely an improvement over no product. But there are other products that give me a lot more volume and texture, which is what I'm looking for, so I will use this up but would not purchase.

Not for me
Sampled

I already have pretty straight and healthy, non treated hair. I rarely need to blow dry it but didn’t realize a huge difference when I did and used the product. I’ve heard that it works really well with treated hair. My mom loves it.
