Designed for fine, thin, or fragile hair that tends to look flat or limp, where the goal is volume and body rather than heavy moisture or damage repair. It's a consumer retail shampoo for regular home use, not a salon-only or medicated product, and suits anyone whose hair struggles to hold volume through the day rather than those dealing with dryness, curl definition, or color-fade concerns.

The case for this shampoo over a generic volumizing product comes down to its ingredient focus: black caviar extract and glycine amino acids are marketed specifically to preserve hair's luster and color while wheat germ protein and hydrolyzed silk protein add body and softness without buildup — a combination aimed squarely at fine, fragile hair that goes limp easily rather than at moisture or repair. Its SLS- and salt-free, pH-balanced formula is meant to boost fullness without the trade-off of a harsher, stripping cleanse.

Wet hair thoroughly, then apply an appropriate amount of shampoo to the scalp and hair. Massage gently through the scalp and lengths, then rinse thoroughly. Repeat if necessary. For additional volume, the brand's Black Caviar volumizing mask or treatment can be used as a follow-up step.

Pros: formulated specifically for volume on fine/thin hair rather than being a general all-purpose shampoo; SLS and salt-free, which tends to be gentler and less drying on fragile strands; pH-balanced formula aimed at protecting color and shine.

Cons: the brand does not publish a full ingredient list, so buyers with specific allergies or sensitivities can't fully vet the formula beyond the highlighted actives; it's a volumizing shampoo, not a moisture or repair treatment, so it isn't the right pick for very dry or chemically damaged hair; the brand's own guidance pairs it with a separate volumizing mask for full effect, meaning a single product may not deliver maximum volume on its own.
