LOVE! LOVE! LOVE!
I have a love/hate attitude with my hair which is probably typical but this rinse pushed the scale significantly toward the love category.My hair is SUPER fine and tangles easily with slight waves in wonky places but overall straight, will NOT hold a curl but is soft and shiny. After using this once (I should note I failed to read the instructions and used it as a leave in and did not rinse) my hair was instantly detangled and has significantly more volume. It’s also still soft and shiny unlike many volumizing products which leave my hair frizzy looking and coarse feeling.It is a bit pricey at $30 (at time of review) but honestly I used a nickel sized amount for my touch the shoulder length bob and with that I think it will last long enough to make it a good value.Next time I’ll use it as intended (rinse out) and report back. I should also mention the tip of the bottle screws off which wasn’t immediately apparant to me. Pleasant earthy scent as well. Would definitely purchase again.

KMS Liquid Strength treatment
This KMS product didn’t do much for my fine, 2a-c curls, but hair product effectiveness is extremely subjective. What doesn’t work for me may be your holy grail, and vice versa. The Alcohol Denat. (second ingredient) means this has the potential to be drying, though being a rinse out formula helps counter that.It smells great, a strong, salon type scent (if you know what I mean) with a hint of alcohol, and the thin formula comes out quickly from the nozzle. I rub it between my hands and slide them through my hair several times to coat as much as possible before rinsing. Without a measuring device, it’s hard to know exactly how much you’re using (recommended 10–20 ml per use), so I just estimate what seems right for my hair. The scent lingers pleasantly most of the day.That said, I haven’t noticed any difference in volume, strength, or thickening. It hasn’t harmed my hair either, so I’ll finish the bottle, but at $30 (at the time of this review), I won’t reorder. I wish I could give half stars, this feels like a 3.5-star product for me. But since KMS is a trusted brand and hair products are so subjective, I’m rounding up to 4 stars. If the ingredients, description, and price appeal to you, you might end up loving it.

No noticeable difference in volume
This rinse is easy enough to use, although instructions could be clearer. I’m unsure whether the intention is to use it with or without conditioner.Lid to the nozzle is very small and could easily be dropped in the shower and end up going down the drain. The product comes out of the bottle quite freely. Instructions state to use between 10 and 20mls of product but there is no way of measuring this, so I just used enough to coat my hair thoroughly. After two washes I’ve already used about one fifth of the bottle, so it’s not going to last for long (I have shoulder length, fine hair).I’m not sure whether this rinse should be left on your hair, or for how long, so I just left it on for a couple of minutes and then rinsed thoroughly.The first time I used it I did not use conditioner afterwards. My hair did feel a little dry and was marginally more tangled that normal. It did look like it had a decent amount of volume after blow drying, although not more than when I use my usual product (which is significantly cheaper than this one, although is not made of all natural ingredients).The second time I used the rinse I used my normal volumizing conditioner afterwards, which left my hair feeling better and less dry. I’m not sure that it’s made a noticeable difference to the volume either with or without the conditioner, but it does feel better with.At £23, this KMS volume strength rinse is pretty pricey, and as I’ve not yet noticed a difference in the volume of my hair between this product and my usual products I can’t really recommend it. Having said that, it’s not awful, so three stars it is.

So Much Frizz
I have long, mostly straight hair. This product has a very strong perfumed smell, almost eucalyptus or cucumber like. It is very runny like water, and does not lather. I used about a fifth of the bottle each time. This caused my hair to be so dry and frizzy. I am trying to repair my hair from the damage of this product. I would not recommend this product at all. I don’t think it’s a good value for the cost considering it damaged my hair and did not add volume.

Help a brother out!
Look, I’ve been on a mission to find a product to help my thinning hair for years. I have tried every product under the sun with zero luck. I picked up this product because the description sounded promising. The smell is a win, there is not some overpowering flower vibe but instead just a light, fresh scent. After a few uses, my hair feels fuller, like it’s got some actual backbone. But here’s my rub: it’s not consistent. Some days my hair’s got that “yeah, I’m looking good” volume, others it’s back to flat-city, and I’m left scratching my head. My issue? The instructions are like a riddle wrapped in a mystery. I’m no haircare guru, so I’m standing there, wet hair dripping, wondering: Wet or dry? Leave it in for a minute or what? A clear “dude, do this” guide would help a guy like me use this stuff right. It does seem to add volume without gooping up my scalp. It was worth a shot if you’re in the same boat but just be ready to engage in some trial and error to figure it out.

Seems to work
I have quite fine hair, that is easily weighed down and made greasy by products. I was pleasantly surprised by this product. I’m not sure if it’s placebo but I do think that it has made a difference. It certainly does not weigh down my hair. The dispenser tip allows a more precise application. However, you don’t get too many uses from the relatively small bottle, so it’s a little expensive in my opinion. As will all cosmetic products I scanned this one through an ingredient checker app and it came back as having largely clean ingredients with some potential allergens but no endocrine disruptors, environmental toxins etc.

Good rinse treatment
Powerful stuff – this reminds me of a highly quality salon treatment post dye work. Smells nice with a bit of astringent overtone. Value for the money is good, and it definitely works as advertised. I have a pretty sensitive scalp and it didn’t cause any itchiness or flare ups. Bottle is easy to use and the narrow tip helps dispensing small and even amounts with every use. I would recommend this product.

Give it a try
Difficult to say how well this works, but it does leave hair leaving soft and has a pleasant scent. Quality seems good, but as for how well it works for thickening hair, I was unable to have a conclusive answer for that.Although it has a pleasant scent and the ingredients look good, I’m not sure if the value is there for a bottle this size. I will say it’s worth a try if you’re in the market to experiment with a treatment like this.

Volume senza appesantire
Buon prodotto, rende davvero i capelli piu corposi e sani, sembra che si sporchino anche meno, l’unico lieve difetto è che rende i miei capelli piu proni ai nodi

It does make your hair thicker
I have fine, thin, curly hair. It can tend to be on the frizzy side. I got this hoping that it would help it look thicker.This is used after washing your hair. It doesn’t say to follow up with conditioner, so I didn’t. The product is a thin, watery product. I used about a quarter sized amount. The instructions did not say how much to use. It does not have a smell. It applied to my hair easily. The instructions didn’t say how long to leave it, so I left it for a couple of minutes and then washed it out. It doesn’t say to follow up with a conditioner, so I didn’t. I then proceeded to dry my hair as normal. I use the same products I always use besides this. My hair was not as soft as it normally is. I chalk this up to not using conditioner. However, my hair does appear to be thicker. Each strand feels thicker and slightly strawlike. Although it doesn’t feel soft to my fingers, it does look good in person.

Natural Looking Volume!
I am always up for a great hair product! This one smells similar to an non-aerosol hairspray with a light fruity//floral aroma. It is very easy to use, but a bit thin (back to that non-aerosol description) which works well since it rinses out quickly after treating your hair. What I like best about this product is that it adds a bit of volume without weighing your hair down. Interestingly, the first ingredient is glycerin (followed by alcohols and water). Glycerin, by itself, could potentially weigh your hair down, creating a greasy and heavy look instead of a thick and luxurious head of hair. What I liked most about this product is that it dried down naturally without any heaviness or unwanted residue.One small note is that the recommended dose is about 10 to 20 ml per application, which gives you about 7 to 15 applications per bottle. This may not make it ideal for daily use unless you cut down on the amount you use. I found that I needed far less than that (maybe about 5 ml) for my short men’s hairstyle. Just something to keep in mind, since you may not need the full recommended amount depending on your hair length.Overall, highly recommended!!

Good but expensive
I quite like this Liquid Strength rinse for my hair.I don’t think my hair looks particularly thicker but it feels stronger.It suggests adding 10-20ml to shampooed hair, which I guess depends on the length of your hair. There aren’t many instructions so I just smoothed it on like conditioner and ran my fingers through it to remove tangles before rinsing. I then applied conditioner to my hair as normal.The 150ml bottle is quite expensive, priced at £20.70 (at the time of review) so it is quite pricey when it only lasts for 7 to 15 shampoos. I do like it but I don’t think I would order it again as it’s too expensive for me.
