Reviews

Perfect hair Day healthy hair perfector is a really nice new addition to my hair care routine!

"I received this product to try with another hair product purchase. I have curly hair that sometimes gets frizzy. This product tames my hair frizziness and makes it soft and shiny. I have been trying Perfect hair Day after washing my hair and in between washes with a little water. Also, it smells awesome! I would like to repurchase it in a larger size."

— Jill B. (5/5)

my perfect hair day

"as other Living Proof products I've tried, this one didn't disappoint. top quality, works as promised"

— alexander l. (5/5)

Super product

"This works very well for my thin hair. It’s makes it smooth and manageable all day."

— Tiffany B. (5/5)

"It made my hair really soft."

— Michelle (5/5)

Excellent product!

"I read some mixed reviews on this Healthy Hair Perfector, but decided I'd try it for myself and see if I saw a difference. Wow - this stuff is awesome. I love that I can use it on my hair after it's dry without leaving it greasy or weighed down. It's also versatile enough to use on damp hair. This leaves my hair feeling so nice and soft, minimizes frizz and flyaways/static cling, and helps my split ends look less noticeable. If you have fine hair and some damage from everyday heat tools or coloring, give this a try! You won't regret it! This is worth every penny in my opinion, and I'll definitely buy it again."

i’ll never financially recover from this.

"got a free tiny sample of this in an ulta hair care bundle like 6 years ago and it was so good that i spent years looking for it (why did you rename it 😩). It’s a serum-y texture, that mostly absorbs within 5-10 mins but completely absorbs overnight (hence the name). this product and a fuzzy sock is all you need for the best overnight blowout of your life, or used before braiding, it will leave you with soft, defined waves that smell amazing. first time i tried it i had to try the rest of the phd line because it was just that good. 6 year later, it still is . TL;DR crack in a bottle."

— Bibi (5/5)

Love!

"My hair feels so much better and more moisturized after using hair perfector. It has become a staple I can’t live without."

— Melanie C. (5/5)

Love living proof

"Love this product. I use 5 in 1 after shower on wet hair. Then I use about a dime-quarter size of this on dry hair until next shower to restore and manage style. Love living proof products. If I try something else, I always come back."

— Donna P. (5/5)

Best hair tamer

"My hair is thick and curly and tends to get frizzy. Using the Healthy Hair Perfector, leaving it in overnight, does wonders for cutting down the frizz, and actually makes my hair softer and smooths down the curls. I use the product about every 10 days and will continue to purchase it."

— KIM C. (5/5)

The frizzy fly-aways vanished

"I have used this product several times and I have been extremely happy with the results each time. Just a little bit of product does away with the frizzy, split end look. Styling is a cinch."

— Ann J. (5/5)

Q&A

Used to buy the nightcap perfector but u no longer have. Is the other perfector to replace the nightcap?
Thank you so much for contacting us, we really appreciate it! Night Cap has been replaced by Perfect hair Day™ Healthy Hair Perfector. It features a similar formula design as Perfect hair Day™ Night Cap Overnight Perfector, but with updated ingredients for more enhanced benefits, and has a fresh, new fragrance. Healthy Hair Perfector is a versatile treatment and is not solely meant for overnight application.
Hi, I like to use the 5 in 1 styling treatment for my styling product when blowing my hair straight. Would I use the Hair Perfector before or after the 5 in 1? Thank you
We recommend applying the Perfect hair Day™ Healthy Hair Perfector after the 5-in-1 Styling Treatment.
Is Perfect Hair Day Perfector gluten free? Can you use the Dry Volume Texture Spray and the Mousse with it? Thank you.
Yes, Perfect hair Day™ Healthy Hair Perfector is Gluten Free. You can certainly use the Full Dry Volume & Texture Spray as well as the Full Thickening Mousse if you desire more volume and texture.
is this the same product as your retired “Nightcap Overnight Perfector”? Is that ever coming back? I LOVED that product.
Nightcap has been discontinued. Healthy Hair Perfector is the reformulated version!
Does this get washed out or you apply before styling? I'm assuming before styling, but I want to make sure.
This does not get rinsed out.
