Each Solidamie shampoo bar weighs between 60 and 65 grams and replaces between 2 and 2.5 bottled shampoos sized 250ml. Depending on your hair length and frequency of use, our customers have been saying It typically lasts between 2 and 3 months. 

No, this is a "syndet" bar, not soap. Unlike soap-based bars that can be harsh, ours is pH-balanced just like high-end bottled shampoo. It features 20+ hair-nourishing ingredients and is formulated without silicones, ensuring a clean finish without the "waxy" buildup often found in traditional soap bars.

We pride ourselves on creating truly pH-balanced shampoo and conditioner bars. Instead of soap, we use plant-derived surfactants (short for surface active agents). While they perform the same cleansing function as soap, there is a major difference in the chemistry:

• Soap Bars: Due to how they are made, soaps have a high alkaline pH of around 9–10. This is too harsh for our hair and skin, which are naturally acidic (pH 4–6). This alkalinity is what leaves hair feeling matted and stripped of color, and skin feeling "squeaky clean" (which actually means it’s been over-cleansed and stripped of its natural oils).

• Our Surfactant Bars: The beauty of a surfactant is that it can be adjusted to the perfect acidic range (pH 4.5–5.5). It binds to oils and dirt to cleanse effectively without causing the molecules to "fall apart" or leave residue behind.

See the diagram below to see where we sit on the pH scale.

While our shampoo bars are packed with oils, we recommend using a conditioner to help re-close the hair cuticles. This seals in moisture, reduces frizz, and ensures your hair remains smooth and manageable after washing.

The most important rule is to keep the bar dry between uses. Use a self-draining soap dish and store it away from direct water spray to prevent it from softening, which ensures you get the maximum number of washes.

Wet your hair thoroughly and either rub the bar directly onto your roots or (don't lather it in your hands first as you are not washing your hands!). Massage the creamy foam into your scalp, then rinse thoroughly—a little goes a long way!
