Directions say to shake before use and apply to wet or dry hair 1-2 times a week. I have long, fine hair (past the middle of my back). With that length plus the sheer amount of hair I have (it's fine but I have a lot of it), I think I can get two months of use out of this. Contains betaine (as a conditioner), Keranutri (volumizes hair), and ACB pisum sativum peptide (also volumizes hair).Has a faint, sweet, floral soap smell in the bottle. I couldn't smell it at all once it absorbed into my hair. Not a bad thing. Also not sticky.I worked a half-dollar-sized amount into semi-dry hair after my post-workout shower. Did not weigh my fine hair down. Even if it doesn't volumize my hair eventually, it will work great as a leave-in conditioner. My hair is so soft!

Highly recommended if you're looking for an affordable leave-in conditioner that doubles as a volumizer for those with thin hair.IG: @addisonsvox

Actually really surprised. The hydrating one didn’t do much but something told me to try this. It genuinely makes my hair strands thicker and stronger without any crunch like keratin does. It’s literally twice as thick and my ponytail is incredible. Holy grail staple off the first bottle. It’s runny like water so I wish it could be sprayed into the hair or more gel like but at least you will never feel it on the surface of your hair - so that’s a bonus.

Before receiving this complimentary, I had no idea The Inkey List made hair care products! Of course when it came in the mail, I HAD to try the Peptide Volumizing Hair Treatment right away. For beginners, I have long, curly, thick hair. My hair is dull, limp, and has been struggling with no volume lately. I am a natural red head, so my hair is virgin. Has your hair been struggling?! Does your hair seem dull? Is your hair limp? Maybe you have fine, thinning hair? Perhaps, all you need is a good hair treatment to bring your hair back to life?

The key ingredients are- Keranutri 2%, ACB Pisum Sativum Peptide 2%, and Betaine 1%. These ingredients are for- Volumizing and thickening, adding volume, and conditioning. This hair serum is vegan, cruelty free, and has sustainable packaging! Even after one use, I am seemingly impressed! This hair serum is easy to use- put a few drops in your hands, rub hands together, lather enough to cover all your strands. I used a little Pre- Wash. While washing my hair, I noticed a HUGE difference in thickness. After my nightly shower, I repeated. Easy to inquire 1-2 times a week. Definitely recommend if you need some TLC for your lovely locks.

I mainly use this treatment for my eyebrows and lashes. And I have to admit, this is the best treatment I ever tried for that said purpose. Both my eyebrows and lashes look healthier, they have more volume, my lashes don't break anymore after using waterproof mascara.Regarding its main purpose - I don't use it immediatly after washing my hair, but on a second or third day on dry hair, like I would normally use a dry shampoo. Since I only use shampoo and leave-in conditioner as my staple treatment, I don't have much of a product built-up and this peptide treatment + bonding oil (or any other nourishing oil) on a second or third day give my hair that typical softness and volume you only have after you wash your hair, at least in my case.I have straight hair.

It's very fine, but at the same time it's heavy and I have a lot of it. I put my hair through a lot of bullshit. Bleaching, coloring, perms, you name it. So at the moment I'm trying to be as minimalistic as possible with my hair care routine.I love the fact that I always feel safe to use The Inkey List's products the way I see fit and most of the time the results are amazing.
Once I got into my 30s, I started noticing a lot more hair in the drain during the shower. Like, a LOT more. I looked around for an option to fight hair fall and found this. I already liked INKEY List, so I gave it a shot. It helped immediately. I think I saw a difference after only two uses. I use it twice a week as recommended (once in the middle of the week, once on the weekend) and I have noticed a significant change in how much hair I'm losing. The bottle lasts a long time because you don't need much, even if you have fairly thick hair. I have already repurchased it once and will again.
I have really long hair, so sometimes the weight weighs down the hair on the top of my head, lessening the volume. The first time I used this product, almost everyone in my household immediately complemented my hair once it dried. I noticed more volume than usual, and my hair does look better than when I don’t use this product. It didn’t leave my hair feeling greasy or oily. Usually when I use products, it sits on top of my hair and feels gross, but this didn’t do that. I’m very glad it works and I will continue to use it.
I experienced a lot of hair loss this past year from a health event and I bought this to add volume to my hair and make it appear fuller while my hair regrows. I did notice a slightly thicker appearance after one or two uses, but I find that the results don't last beyond washing day. I also wouldn't say that my hair feels thicker at all. I do really like that it doesn't leave any residue on my hair or dry it out at all and it's easy enough to use, though a spray applicator may be helpful. I have fine very wavy hair and I had the best results when applying it after my leave-in conditioners but before styling products.
3.5 but could bump it up higher with further use and more visible results. I have used this hair treatment about 5x post shower before any other hair products. As a lady with fine hair, more oily scalp and drier ends this product does NOT make my hair feel ANY different. I can barely tell I put anything on it. Which is nice. I hate my hair feeling weighed down. I do notice my hair softer to the touch and bouncier. For the price and result; I am happy with my purchase. I hope by the time I empty the bottle I will see even better results.
I have used two times on wet hair before adding my hair gel. I follow curly girl method, but with aging have some hair loss top of scalp. I don’t like to use hair fibers because I don’t like to wash my hair everyday and I usually air dry on way to work. I also like scent free products which are hard to find. This product was easy to use blended nicely in the roots and crown area. No residue or weighing down of curls still styled the same as usual. I also appreciate the fragrance free products for both skin and hair. I am impressed and pleased with the effects and my scalp is less visible with more volume , but still soft. Very pleased. Price awesome. Love the skincare as well.
I have fine, thinning wavy hair and this helps create amazing wave definition without weighing my hair down. I apply about a coin sized amount (for my shoulder length hair) to wet hair then scrunch to form waves, then add mousse but sometimes I’ll just use this on its own and my hair looks great. Just let it air dry and then gently scrunch out any crunchiness in the hair from the dried product and voila! I’m now on my third or fourth bottle of this so god knows what I’ll do if it’s ever discontinued. I think it does help with volume but the main thing for me is the waves!
