A: Hi Trish,
Yes, a teenager can use this. It is labelled for adult use only because the spray dispenser is not recommended for young children.
I hope this helps!

A: Yes and so can adults. Hopefully they will not find the fragrance unpleasant as it does have a musky scent.

Smells terrible
Smells terrible. How anyone can walk around with their hair smelling like this is beyond me. I don’t even know if it works, the smell almost made me puke and I won’t be using it.

Effective and pleasant fragrance
This is REALLY effective! Makes my hair shiny and stronger and light fragrance is not overpowering, dissipates after drying. My hair tends to be dry and breaks easily but this is helping to resolve those issues.

Leaked in shipping
Haven’t tried it yet but it wasn’t twisted all the way closed so it leaked in shipping on the box and other items and theres some amount missing. There wasn’t a seal on the inside since there’s a small insert. The photo with my finger points to where the liquid line is. So it’s a bit disappointing out of the gate. Hoping it works though!!

Excellent!
It makes my hair feel thicker and healthier. It's nice that a hair protect is included in this leave-in. I save money and protect my hair without having to buy another product.

Game changer
This does everything it says it does. My stylist recommended for oil free moisturizing products to use before styling. I like to use the Hask keratin deep conditioner first then this after along with my other oil based leave in because i have thick wavy hair. These two really help hydrate and smooth my hair. It looks fuller in spots that are/were thinner. My hair is looking the healthiest and best since I incorporated these two products. Never going back, hair is finally retaining length and growing healthier.

I use this product with the Hask tea tree and rosemary shampoo and conditioner and can see a significant difference in my hair! Will continue to use this line of products.

Smells bad
This smells like medicine/vitamins. I sprayed it on my hair a few times and did not see a noticeable difference. 2 stars for the thermal protection at least. Do not recommend buying, try another product that at least smells nice. Got on sale so it’s not too bad.

My hair loves this
Love that it's lightweight yet still adds body and volume. I have fine and thinning type 3 curls and it works great for me.

5 in 1 spray
It detangles my hair, leaves a nice shine, gives me definition to my curls & body, plus adds some thickness. I am hooked on it. Be generous with the spray.

Benefits out weigh strong smell
4.5 stars. I took off a half star because the coffee scent is so strong. It smells good but it can clash with my perfume. However I still think this is a great product. It leaves my long fine hair soft, shiny and detangled without weighing hair down. On the rare occasion I bust out my blow dryer it helps my blowout last a whopping three days. I will purchase again. Thanks again Hask!

It smells amazing!!!!!!
I've yet to see how well the product works... but it smells amazing. so far after 30 minutes it's taken away most of the itch that comes with breakage so I'm looking forward to seeing how much it works. ❤ no itch means no scratch which means less breakage/loss.

Doesn't leave your hair soft. More like sandpaper

The SMELL! Horrible!!
When I read in other reviews that this smelled like coffee, I thought... I like the smell of coffee! Well... Its so horrible and so strong, I had to wash my hair on my lunch hour from work. I'm not using ever again and certainly not ever buying again. Blecchhh!

Great product
No tangles, no greasy feeling/residue, smells great. Been using for several months and love this line of hair products. Disappointed at how hard they are to find in stock!
