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.

So good

Got this as a free sample with my purchase and love it! I don't always blow dry my hair but when I do, I like to use PHD 5 in 1.

Amazing!

I have a lot of thin hair and when I do a whole routine of volumizer and oil, my hair gets greasy. But if I use less, I don't have a lot of volume or softness. This product does it all without any greasiness and it's light weight.

I have fine, lifeless hair. "Perfect hair day" really does live up to it's name because that's exactly what I get when I use it. The smell is delightful too!

An all in one wonder product!

I am in love with this 5-in-1 product. With consistent use it has really improved the my hair. My hair is stronger, smoother, and definitely helps protect against early fading. My hair dries quicker and feels soft even after using a straightener or curling iron.

Got the sample, purchasing the full size

Got the sample and was wowed. I blow dry my hair often and have used different heat protection and styling tools and this was a clear standout. My hair kept a soft, touchable quality but the volume, shine, and hold were outstanding. My hairdo lasted most of 3 days with just minor brushing/touch ups.

Okay

Not the best blow-dry stuff I've tried, not the worst. Doesn't make my hair greasy like some, but I didn't feel it made it especially volumized or anything else that I'll probably buy it again.

My Fine Hair Loves This!

So, I always hated the time at the salon when my hairdresser was ready to slather some styling product into my ultra fine hair. I was always left with a heavy, almost greasy feel to my hair and would want to go home and immediately wash it. Then this little beauty shows up in my Birchbox! A little goes a long way, but that little bit is everything! No heaviness, no greasy feeling, no complaints! My hair has extra shine and volume and just the right amount of added weight with just a little extra oompf to hold my blow dried style!

Great Product

My hair is fine and thinning and this product made my hair soft and manageable with lots of volume. Next day my hair still looked good! The sample was a good size. I hope to be able to find this product elsewhere since you website says it is no longer available.
