Fine hair is a master of the vanishing act — full and bouncy walking out of the salon, flat against the skull by Wednesday. Fat muk Volumising Shampoo starts the fight back at the basin, before a single styling product gets involved.
TL;DR: A weightless, gel-based shampoo that cleanses the scalp and expands the hair shaft, so fine and limp hair comes out thicker, stronger and genuinely fuller. It builds fullness, texture and shine without the residue that flattens roots by mid-morning, and it's mild enough to use every day. The 1 litre is the salon-size bottle for anyone who has spent years quietly hoarding volume products.
Product Details and Benefits
- Weightless gel formula. A light gel rather than a rich cream, so it cleanses without leaving behind the film that quietly kills volume at the roots.
- Expands the hair shaft. Each individual strand is plumped, which is what makes the whole head read thicker rather than simply cleaner.
- Thickens and strengthens. Body with structure behind it, not a temporary illusion that collapses the moment the blow-dryer switches off.
- Fullness, texture and shine. Volume ranges usually leave hair looking dry and matte. This one adds grip and body while keeping the light reflecting off it.
- Refreshed scalp and roots. Cleanses the scalp properly, which matters more for fine hair than any other type — oil at the root is where flatness begins.
- Built for fine, limp hair. This is the intended audience, and the formula is engineered around it rather than being a general shampoo with a volume claim attached.
- Still gentle enough for fragile hair. Suitable for all hair types, including dry and damaged hair, and mild enough to use daily.
- Works across the board. Curly, wavy, frizzy or straight. Coloured, blonde, grey or untouched.
- Inside the bottle. Glycerin holds moisture, panthenol (pro-vitamin B5) conditions and adds body, a hydrolysed collagen derivative supports the strand, and polyquaternium-10 leaves a light conditioning film without the weight.
- The scent. Alpine mist — cool, crisp and clean, with none of the sugary sweetness the volume category usually defaults to.
- The size. A 1 litre basin bottle from muk, an Australian-owned brand that does not test on animals.
How to Use
- Wet the hair thoroughly with warm water. Gel formulas need proper saturation to spread and lather properly.
- Dispense one to two pumps' worth into the palm.
- Massage into the roots with the fingertips, covering the entire scalp. This is the part most people rush, and it's the part that matters most for lift.
- Work the lather down through to the ends.
- Rinse thoroughly under warm water, and repeat if the hair is heavily product-laden.
- Squeeze out the excess moisture and follow with Fat muk Volumising Conditioner.
Pro tip: Volume is won at the towel-dry stage, not in the shower. Once you've washed and conditioned, work Fat muk Volumiser through towel-dried hair with the nozzle aimed at the root area, then blow-dry. The shampoo does the expanding, the volumiser holds that lift in place, and the humidity-resistant formula stops the whole thing dropping the second you step outside.
Why You'll Love It
Thicker, fuller, shinier hair that still feels like hair, from a shampoo light enough to use every day without a hint of build-up. It gives fine hair the body it has been faking with dry shampoo and prayer, and the litre means you can stop measuring it out by the teaspoon. Add it to your cart and let your roots do the standing up.
