Fine hair reacts to everything. Too much conditioner: flat. Too heavy a shampoo: flat. Even the wrong shampoo bar can make fine hair heavy and limp instead of light and voluminous. At the same time, fine hair benefits most from switching to a good shampoo bar, if you choose the right one.
Why silicones are the problem for fine hair
Most liquid shampoos contain silicones (Dimethicone, Cyclopentasiloxane). Silicones coat the hair shaft and give an initial smooth feel, but build up over time. For fine hair that means increasing weight on a hair shaft that already has little volume. Hair becomes heavier, flatter and loses its natural structure.
Nature Bar shampoo bars contain no silicones. No build-up, no weight, no downward spiral of needing more and more product.
What works for fine hair in a shampoo bar?
- No silicones — prevents build-up and weight on the hair shaft
- Mild but effective cleansing — fine hair needs sufficient cleansing, otherwise it quickly becomes greasy and flat
- pH 5.5 — closes the hair cuticles, gives shine and structure without weighing down
- Volume-enhancing ingredients — spent grain contains proteins that temporarily thicken the hair shaft and add volume
Which shampoo bar for fine hair?
The Shampoo Bar Strength & Volume is the best choice for fine hair. Made with spent grain from an Amsterdam brewery: a circular ingredient that naturally contains proteins and B vitamins. pH 5.5, no silicones, no sulfates. No transition period. Switch directly from your current shampoo.
Tips for more volume with fine hair
- Wash with lukewarm water, not hot. Hot water opens the hair cuticles and makes hair heavier
- Rinse with cold water to finish. Cold water closes the hair cuticles and adds shine
- Apply conditioner only to the ends, not the scalp or roots
- Let your hair dry naturally as much as possible
