Q: Do I apply this to my roots or just to the ends of my hair I am looking for something that will help with dandruff

submitted by Joanan - 1 month ago
  • A: Hi Joanan, Great question! After shampooing, coat the strands with your custom hair mask from mid-shaft to ends. We recommend using a wide-tooth comb to ensure an even application.

  • A: Hi Sophie, Our Straight Hair Mask is formulated with seaweed extract known to amplify silky shine for soft and healthy looking hair. This mask is created for straight hair types and is not designed to straighten hair. Popular #hairgoal booster shots for straight hair include Strengthen, Volumize, and Deep Condition - but the world's your oyster!

Q: do you use this before or after shampooing

submitted by emily - 8 months ago

Q: is this gonna turn my frizzy hair to straight

submitted by Lisa - 1 year ago
  • A: While our products are not intended to change the natural structure of your hair, they can absolutely help to banish frizz! We recommend adding the 'anti-frizz' booster to your set.

Q: What is the reason only 3 shots can be added? what would happen if 4-5 shots were added?

submitted by Sarjane1983 - 1 year ago
  • A: Hi there, Gosh, that's a lot of hair goal love :). We recommend keeping it to 3 #hairgoal booster shots. It is not currently possible to put more than 3 #hairgoals in each bottle and still be able to mix evenly. We're confident you'll find that 3 hair goal booster shots can cover your...well, hair goals!

Amazing hair mask! This hair mask was amazing for my very thick straight hair. I loved how smooth and soft it made my hair. It was one of the best hair masks I’ve ever used. I really hope they bring it back in stock.

I have ultra-fine, straight hair. I also have a lot of it. My hair texture is just super super fine and thin in texture. It is extremely hard to find conditioners and masks for healthy hair that do not cause quick buildup or oily/greasy hair. This was my HOLY GRAIL and now it is DISCONTINUED!!! I used to pair this up with the hydrating boosters (the blue one, it happened to match) and it turned my hair from struggling to thriving. I am so upset and I have yet to find a dupe. I wish they would bring this back. I literally cannot use anything else because it either has gives really bad texture, or is too much for my hair. Some products make my hair sticky and slimy while others make it look like I never washed or used deep fryer oil on my hair. Please bring this product back. It was amazing for the price, smelled so good, and worked!

I swear i'm never one to write reviews, but this stuff is so absolutely amazing & i'm very picky with products. I used it as my conditioner & it made my hair feel so amazingly soft, & the scent was delightful. I wanted to order it again but its been out for a while now & i'm praying & hoping that this isn't discontinued ): I saw that they are now selling at sephora, but their pro line, & the ingredients are not similar to this! Please bring it back to target! - coming from someone who has fine thin hair all her life

I've been using this shampoo and conditioner line for about a year and saw this hair mask, later. I decided to give it a try. I love it. I wash my long, straight, blonde hair about 1-2x a week. I use this mask once a week after the conditioner. Smells amazing and my hair feels smooth and soft. It's affordable too. I have not complaints. My hairdresser says my hair is in really good condition as well. I'd recommend this product.

This is a holy grail in my hair care routine. Not only is it so affordable, smells great, and holds a good amount it works wonders for my hair. I have dyed my hair through and through and this helps bring it back to life every time. I use it in replacement of a conditioner.

I know everyone is different but this product stung my scalp and skin! It gave me a mild chemical burn on the sides of my face where the product rinse off happen. My face unfortunately got extremely red and bumpy/patchy on the burn spots. I am not someone who has sensitive skin either. My scalp has a burning sensation after the first use.

You know how sometimes when you wash your hair away from home and maybe the mineral content of the water is different or something and your hair FREAKS OUT? This happened to me, I couldn’t even get a brush through my hair without tearing it all up, and getting home and using my usual products didn’t fix it, so I went looking for some kind of deep conditioning mask to try. I picked this Function of Beauty product because I’d used their shampoo before and liked it reasonably well & it wasn’t too expensive, and I have to say 10/10 I was able to air dry and brush my hair to smoothness after using this and it’s a huge relief. It smells nice and my hair feels really good.

[This review was collected as part of a promotion.] I loved the way this made my hair feel. I tried it once with it by itself, prior to mixing in two of the different booster shots... it doesn't weigh my hair down or make it feel greasy like a lot of other masks tend to do. Now to get the shampoo and conditioner to try them out as well.

This has worked really well to follow a clarifying shampoo! Makes my hair feel soft and strong, without making my roots feel gross. I have thin, fine hair but a lot of it, and it’s blonde so I hate when my roots look greasy!

Definitely a brand that surprised me in the best way. This mask is AMAZING. Not only does it smell like heaven, but I actually works. My hair feels so smooth, fresh, and healthy. It looks straight and with a notorious frizz reduction without looking flat or weigh down. Definitely recommend. Complimentary from Function of Beauty.

I recently received these products complimentary from function of beauty & I absolutely love how this mask makes my hair feel. I have very fine, thin straight hair but it gets a bit frizzy. This mask hydrates my hair, but doesn’t weigh it down and keeps that frizz away. This hair mist after I get out of the shower just adds to the softness of my hair and makes it super manageable!
