Biotin Clarifying Dry Shampoo Tap Secret Refill Set - Travel Size

Our review of the Tap Secret Refill Set finds it best suited for anyone who wants a compact, non-aerosol dry shampoo that genuinely reduces scalp oiliness while adding volume. The limited edition refill set combines a 0.24 oz tub and a refill of ultra-fine powder that is benzene-free and hypoallergenic, making it a practical choice for travel, gym bags, or quick refreshes between washes. The single biggest reason to buy is the high oil absorbance and noticeable volumizing effect delivered without spray propellants.

Key Features

• Non-aerosol powder: The dry shampoo comes as an ultra-fine powder in a tub and refill format so it refreshes roots without propellant sprays.
• Benzene-free formula: Formulated without benzene to offer a cleaner-feeling product for those who prefer non-aerosol options.
• Biotin and black ginseng: Enriched with biotin and 0.1 ppm black ginseng to help support root strength while absorbing oils.
• High oil absorbance: The fine powder effectively soaks up excess oil, sweat, and dirt to extend time between washes.
• Dermatologically tested: Clinical testing reported a strong reduction in scalp oiliness and improved hair volume in participants, indicating gentleness and efficacy.
• Travel friendly size: The 0.24 oz tub plus refill fits easily in small bags for on-the-go touch ups and is suited as a stocking stuffer or gift set item.

Who It's For

This product is ideal for people with normal to oily scalps who need a compact, effective oil absorber between washes, especially those who prefer a non-aerosol option. Travelers, gym-goers, and anyone who values a small, refillable tub will appreciate the convenience and the hypoallergenic claim.

Those with very light or platinum hair tones should test color match first, as some users report a slight color shift on light shades; people seeking a scented, spray-style dry shampoo or larger refill formats may prefer different products.
