A brush that snags after washing, frizz as soon as it gets humid outside, or loose hairs flying in all directions after blow-drying: KMS AllSmooth Smoothing Lotion 150 ml was developed specifically for those kinds of moments. This lightweight leave-in instantly makes hair easier to comb, helps control frizz, and provides a smooth, soft finish without silicones.
The lotion combines care and styling preparation in one step. You apply it after washing and leave it in the hair. Then you can let your hair air dry or blow-dry it. If you regularly use a hairdryer, straightener, or curling iron, the built-in heat protection up to 230°C is an important advantage.
KMS reports that using the Smoothing Lotion makes detangling up to 3 times easier and leaves hair 2 times smoother compared to untreated hair. Additionally, the formula helps seal hair cuticles and split ends, and protects against humidity and the frizz it can cause.
You will notice the first difference as soon as you comb through. The lengths become more supple and the comb or brush glides through the hair more easily. During drying, the lotion helps keep the hair smoother and tames loose, unruly hairs. Thanks to the anti-static effect, the hairstyle takes on a calmer and more well-groomed appearance.
Moreover, this is not a heavy oil or a rich mask. It is a leave-in smoothing lotion intended to stay in the hair and become part of your normal styling routine. That makes it especially handy when you want care, anti-frizz action, and heat protection after every wash.
AllSmooth Smoothing Lotion is interesting if your hair is difficult to detangle after washing, frizzes easily, or is hard to style smooth. KMS gives the product a wide range of applications, from straight to curly hair .
So, you don't need to want a completely straight hairstyle to use this lotion. The formula can also be used on wavy, curly, or frizzy hair when you primarily want to improve manageability, reduce flyaways, and gain more control over frizz.
The lotion is particularly suitable for:
You might be familiar with the effect: at home, your hair looks perfect after blow-drying, but outside, in humid weather, it starts to frizz again. Hair with a less smooth outer layer can react more strongly to ambient moisture.
The Smoothing Lotion helps seal the cuticle and split ends. This gives the hair a smoother surface and protects it against humidity and frizz. At the same time, the anti-static effect helps prevent loose hairs from sticking out in all directions.
That makes this leave-in not only useful for detangling immediately after washing, but also as preparation for a smooth blow-dry styling that stays better under control .
Practical tip: start with a small amount of product. Naturally, you need less for fine or shorter hair than for long, thick, or very unruly hair. Distribute well first, and only add more if the lengths require more product. This keeps the result airy.
Those who regularly style with heat do not need to add a separate step for basic heat protection with this leave-in. KMS states that the Smoothing Lotion protects the hair against temperatures up to 230°C .
To do this, apply it to towel-dried hair before drying and heat styling. The same step that makes hair easier to comb through and reduces frizz also prepares the hair for the use of heat tools.
In the renewed AllSmooth formula, KMS uses upcycled olive . In doing so, material is reused as a valuable raw material instead of being lost. Within AllSmooth, this ingredient is used in formulas developed to intensively nourish the hair and make it smooth and soft.
The formula also contains shea butter (Butyrospermum Parkii Butter) . Anyone who consciously looks at what is *not* in a hair product will find no silicones, mineral oils, dyes, PEGs, or SLS/SLES sulfates in this lotion.
The current KMS AllSmooth Smoothing Lotion is vegan : according to KMS, the formula contains no ingredients of animal origin. The product is also designated by KMS as PETA-approved.
KMS uses upcycled natural ingredients for the AllSmooth line and states on the standard packaging that the product is CO2-compensated. According to the brand, all packaging materials used by KMS are recyclable. Always follow local waste guidelines for separating and recycling empty packaging.
Within the AllSmooth range, there are several anti-frizz products. They do not all have the same function. The Smoothing Lotion makes particular sense when you want to detangle, smooth, and prepare the hair for drying and styling immediately after washing. You apply it to towel-dried hair and leave it in.
Within the same line, the AllSmooth Weightless Anti-Frizz Serum is specifically aimed at a weightless, anti-static effect and, according to KMS, is particularly suitable for fine to medium hair. The Intense Nourishing Oil is richer and intended for extra nourishment and shine, especially for medium to thick and unruly hair.
So, if you are primarily looking for a frizz-fighting leave-in that simultaneously detangles and protects against blow-drying and styling heat , the Smoothing Lotion within the AllSmooth line is the most obvious choice.

The strong point of this lotion lies not in one spectacular styling function, but rather in the combination of multiple practical properties. After washing, you often have to deal with tangles, fragile wet hair, frizz, and the heat of a hairdryer all at the same time. The Smoothing Lotion tackles these steps in a single leave-in product.
If you have fine hair, definitely do not automatically use the same amount as someone with thick or long hair. A thin, even distribution through the lengths is usually more effective than a lot of product in one spot. For thick, curly, or unruly hair, you can gradually increase the amount until the hair is easy to comb through and manageable.
And don't expect a straightener in a bottle: the lotion does not change your natural hair structure. Curly or wavy hair will not automatically become straight. What it does do, however, is make the hair easier to manage, reduce frizz, and create a smoother base for the styling you choose afterward.
