Wasn’t a fan
Originally posted on influenster.com
[This review was collected as part of a promotion.] No slip again to this conditioner I’m not keen on this type of jar style vessel when having to use in the shower, this type of pot is better for leave in conditioners than you can use outside the shower. The smell was quite botanical not unpleasant. But as a conditioning mask I didn’t feel my hair gained anything softness/detangling or any other benefits. I won’t be using again.

Perfect
Originally posted on influenster.com
[This review was collected as part of a promotion.] I recieved this haircare mask free from influenster in exchange for my honest review. I combined using this hair mask with the shampoo and my hair felt soft but full of volume i was extremely suprised after using this. The pink tub looks like a premium product and the consistency of the mask is very thick which is great because it doesnt drip. I used a small amount and applied to wet hair where i left it for 5 minutes and then combed the product through my hair. I then rinsed it and left it to dry naturally once it was fully dry my hair felt fuller especially at the roots and i definitely noticed how much more volume and body my hair had. The smell of the mask wasnt what i expected but it wasnt strong enough to be off putting because for me the results were amazing.

Glam and classy in a box
Originally posted on influenster.com
[This review was collected as part of a promotion.] Absolutely love the packaging colour, gold print and matte pink tub. It’s just eye catching and attractive so I’m drawn to it. My hair has been neglected recently since I had my son so I was interested to see if the hair mask would make any difference. I certainly felt my hair was softer, effortless more volume and shining. Certainly less split ends than I had imagined as well. The scent is beautiful as well and lasts my kids were constantly smelling my hair. Great product for a luxury feel

Works really well
Originally posted on influenster.com
[This review was collected as part of a promotion.] This has really stylish packaging, the product itself has a lovely rich texture and a delightful smell. I've tried this a few times after particularly frizzy/dry hair days and it's worked really well for me. It's quite possibly added more volume to my hair than the conditioner in this range did (not a necessity for a thick-haired girl like me but a nice bonus) and certainly left my hair feeling gorgeously soft. Definitely recommended! (Incentivised)

Leaves hair soft and smooth
Originally posted on influenster.com
[This review was collected as part of a promotion.] Nicely packaged hair mask, thick and does not drip. Coats hair well and after 5 minute hair felt nourished and smooth (notable reduction in frizz when dry). One negative was the smell, it could be slightly more perfumed for my preference but overall excellent hair mask.

Went on well but left hair frizzy
Originally posted on influenster.com
[This review was collected as part of a promotion.] I got this product free from hair by Sam McKnight and influenster. It came in a nice red tub inside a nice red box. I washed my hair as normal then applied the treatment mask and followed the directions. The consistency is really nice and went on my hair lovely but I did not particularly like the smell and would have been nice to have a fruity or nice floral scent rather than the chemical smell I picked up. It rinsed out well but did leave a kind of sticky feeling to my hair, once dried with a towel my curls were more defined but once it was fully dried the curls were less defined and my hair was frizzy. It has given my hair the look of more volume and feels softer but has not helped with split ends but maybe with continuous use it will improve. I will finish off the tub as I don't like waste but won't be buying in the future due to not liking the scent and how my hair was left frizzy.

Nourishing for dry hair
Originally posted on influenster.com
[This review was collected as part of a promotion.] I have thick, dry hair that has a tendency to frizz, this conditioner with a nourishing blend of squalene and voluminis is gorgeous to apply, working its magic right away. It takes 5 minutes to treat and my hair feels noticeably softer , looks shinier and is much bouncier and easier to style as a result. The floral scent is beautiful and your hair smells amazing for the longest time! I would definitely recommend!

Lovely mask
Originally posted on influenster.com
[This review was collected as part of a promotion.] A really nice smelling hair mask, a little went a long way. It made my hair soft and was a real treat for my routine. I’m not sure if it added a lot a volume to the hair I will see over the next few uses, it was a pleasure to apply. The container could get a little messy so I was careful when applying.

Revs up the volume!
Originally posted on influenster.com
[This review was collected as part of a promotion.] A lovely fresh citrusy conditioner which applies, absorbs and rinses well. Admittedly I have big hair in any event and a lot of it but I do lack root lift and volume immediately from the base (probably from scraping it back all the time) but this product definitely helped with that on the first application. However, I don’t think it is as obviously nourishing as it could be and it hasn’t left a smooth finish unfortunately. I’ve found my hair has been quite frizzy and fly away since using it which would put me off using it in future. The packaging is however lovely and I like the branding. It’s sleek and modern and the products have memorable names

Tried better
Originally posted on influenster.com
[This review was collected as part of a promotion.] Ive used it with shampoo.grom the same brand. Tbe shampoo was terrible. Your hair were very stiff and like fake to touch so after applying this conditioners they were going back to previous stage but not better. The hair looks dry but also as you be hot more.

Luxurious hair care
Originally posted on influenster.com
[This review was collected as part of a promotion.] This is so easy to use. Simply apply a decent amount to your hair after shampooing, leave it for at least 5 minutes then rinse. It's a nice thick cream (not too runny) so it holds really well. I do love the way it's made my hair feel. Quite luxurious. The only downside for me is the scent is way too strong. But that is simply personal taste.

Very efficient treatment!
Originally posted on influenster.com
[This review was collected as part of a promotion.] I recently had to bleach my hair and treatment mask was an extraordinary help! It made my hair soft and very manageable, giving it volume and body. I use the mask of towel-dried hair, I apply the mask and then I leave it on my hair for about 30 minutes, with my hair wrapped on a dry towel. I do recommend it to everyone with bleacher/damaged hair. The results are amazing!

Works wonders on my thin hair!
Originally posted on influenster.com
[This review was collected as part of a promotion.] I absolutely love the HAIR BY SAM MCKNIGHT BIGGER LOVE TREATMENT MASK. First of all, the packaging is simple yet beautiful with those lovely golden details on the label. The scent of the mask is amazing, it's fresh and not artificial, and I find myself wanting to smell it over and over. I'm a bit lazy when it comes to hair care, so I appreciate that I can simply apply this mask to wet hair, leave it on for 5 minutes, and then comb through. However, there are times when I indulge in a longer bath, and leaving it on for an hour works wonders! My hair becomes incredibly soft, smooth, and bouncy. It doesn't tangle as much, and it definitely adds volume and freshness that lasts longer. After using this mask, my hair feels noticeably stronger, looks shinier, and is much easier to style. I'm impressed, and I'm sure I'll be buying it again!
