I could immediately see the difference in my hair. The hair looks well-groomed and soft. I gave a star less because of the price for 15ml. I like that K18 Molecular Repair has more positive results for hair and that it is a leave-in mask.

Very fine hair mask, makes the hair super soft and shiny and the scent lingers for a long time. There is a lot in the pot and so you can take it for a long time. My hair is soft and not too heavy after use. Definitely a must.

Unfortunately, if you have fine hair like mine that’s also highlighted, even a small amount of this product can make it feel not per ce greasy, but definitely heavier and require washing a day sooner. I know friends who swear by it, but their hair is thicker and has a different texture. For the price, I’d recommend sticking with Olaplex No. 6 or Redken Acidic Bonding and applying Pureology Color Fanatic after towel-drying.”

My hair feels amazing after every use, I can feel and see difference from how my hair was once I started to use this product. It helped me with all the heat and coloring damage, my hair definitely looks and feels shinier and healthier. I am using hair extensions, it works good in both extensions and my real hair. Only downside of the product is the price of it, as it is quite expensive, it is worth it if you can afford.

You will not believe how GOOD this hair mask makes my hair feel! I double shampoo, then use a grape size amount of the hair mask on my hair, rinse it out without waiting, and my hair feels silky smooth and so light and it smells ABSOLUTELY PHENOMENAL. I wish you guys could smell how good it is. Japanese haircare is next level I swear, I’m so close to buying the &honey stuff because im now addictedddd. I can’t stop smelling my hair and it just feels so light and bouncy and silky and shiny and EVERYTHING. Unfortunately it hasn’t helped with my battle with frizz lol but it’s helped with my battle with DULL, heavy, and dehydrated hair. Tip: if you have high porosity hair, use the fino hair mask! If you have low porosity use tsubaki. Not the other way around, especially if you have low porosity hair, because fino has too much protein for your hair!

The packaging looks premium, it's suitable for a gift idea as well. It's smells really lovely. The texture is quite good and its easy to spread all over my hair. I'm quite happy with the results. My hair stays nice and fresh longer then usual. It gives a good care to my hair. Definitely looks better after the mask. People should really consider trying it.

After washing your hair with just shampoo, once your hair is towel dry you are to work this product through your lengths. Leave in for 4 mins before adding in other hair heat protecting products and drying (activating). I’ve been using this every wash for the past 2 months and I haven’t noticed a difference with my hair… if anything my hair feels rattier!! But I’ll still it, incase it’s cumulative.

Ok, I’ll start by saying it’s expensive, and there are other hair masks that can give you great results for less. That being said, I love this mask. It really makes my thick, frizzy, bleached hair very smooth and soft, detangles it and leaves it silky and manageable. The packaging is also very nice and I plan on refilling the tub after I’m done (wish they’d do refills though)

I tried out the Gisou Honey Infused hair mask. As soon as I opened the packaging, I was really satisfied with both the hair mask's efficacy and its packaging. The packaging itself looks luxurious and classy and the aroma of the honey was quite pleasing. The mask itself is quite thick and the texture makes it simple to distribute evenly throughout my hair. After applying the hair mask, I left it on for the time required and instantly my hair felt really smooth and soft. It gave off a visible, long-lasting natural shine. The capacity of this hair mask to deeply hydrate and nurture my hair is one of its best qualities. My hair is normally dry and frizzy, but this mask really helped to control the frizz and make my hair easier to handle.

This is the first hair mask I have ever used. Really easy to apply, smells amazing and is easy to wash out. Makes my hair smell and feel amazing. Comes in a lovely box. Well worth the money. Can be used on all types of hair. Doesn’t make your hair feel greasy.

So when I first started using this I hated it, I felt like my hair was actually drier and I couldn't figure out why. I thought you weren't able to use conditioner or leave in masks with it but you CAN! You just have to wait for 4 minutes for it to activate and then you can use a conditioner - now I love it. Hair feels healthy and stronger. Def recommend

This product is amazing you can use it on 3 ways. I use it as leave in conditioner and add to my curls when dry. The smell is amazing and the way it makes my hair feel is great. You only need a little bit. It makes your hair soft and helps the curls less frizzy

I bought this while visiting London thanks to a staff member’s recommendation. She said she uses it every week and leaves it on for 30min to a few hours (unlike the pack instructions*). So I decided to give it a try and leave it on for an hour or so, washed it off and immediately felt softness and saw my hair look shinier. I thought to myself it could’ve easily just been a placebo effect…a day later and one of my colleagues says she loves my hair because it looks so soft and shiny! *If you’re going to use it for longer than what the bottle says, be careful how long you use it for because it made my hair really stiff the longer it stayed (I think I left it on for 2 hours when that happened)

I have long very dry hair full with clinch. Since I started using k18 I have seen a lot of difference with my hair. My hair they are softer and stronger with more shine and they don't break as much as they used to break before. I'm really satisfied.

I seriously need help with my thinning hair it’s horrible to see it thinning so much lots falls out it’s course and dry my scalp is also dry and sensitive not a great look or feeling

I started using this and after a month I only saw slightly less breakin but the bottle was already out. I think it was good but a little pricy for such a small quantity. I have medium size hair and had to use at least three pumps and not the 1-2 recommended

Have used this product many times when I feel I need to revive my hair a bit. I leave this mask on my hair overnight. Given 4 stars because I have quite long hair and to fully saturate it I have to use quite a lot of the product so wish it went a bit further.

after reading some of the reviews, I had to try it out for myself.  When I was a kid I always struggled with my hair as I was allowed access to bleach and dyeing it ect..  this caused my hair to be absolutely fried. Two weeks into using this product it did NOTHING for my hair. I was so dissatisfied. 

All ESPA products are amazing. I used to work in a spa that used these products and on occasion had the chance to try them out myself. I bought the brand as I wanted to give it a go at home and I have not turned back to any other brand. The tonic is amazing and the hair and scalp mix is amazing for those who have dry skin.  Not only can it be used in the hair it can be added to aggressive exfoliating products that can cause irritation, and also as a face mask if you have sensitive skin. 

My absolute favourite hair oil of all time! Wella is an amazing brand and this is one of my favourite products, it smells beautiful, leaves the hair feeling lovely and soft, smooths any flyaways and is light enough for everyday use, overall a great product, i would highly recommend!
