Key Ingredients

Hair Suitability

This product is specifically designed for those with fine, limp, or thinning hair who want to add thickness, body, and volume. It is formulated to address hair that falls flat and to strengthen weak, fine hair that is prone to breakage.

The formula is sulfate-free and paraben-free, and is described as lightweight so it will not weigh hair down. Those who need to avoid contact with eyes should take care during application, and the product should not be used near heat or open flames due to its flammable nature.

Usage Tips

• Shake the bottle well before each use to activate the formula.
• For external use only; do not ingest.
• Avoid spraying near the eyes, and if contact occurs, rinse the affected area immediately with water.
• Keep the product away from heat sources and open flames, as the formula is flammable.
• Do not rinse the product out after application; leave it in and style as usual.

Daily Styling Routine

The HASK Biotin Boost 5-in-1 Leave-In Spray is designed to be used as a pre-styling primer on freshly washed hair, giving fine or limp hair a fortified base before any heat styling.

1. Wash your hair as usual, then gently towel-dry so hair is damp before applying the spray.
2. Shake the bottle well to activate the formula before each use.
3. Spray generously onto damp, towel-dried hair, working the mist through your strands.
4. Comb through to distribute the product evenly - do not rinse out.
5. Style as usual - the spray acts as a heat-protective primer, so you can blow-dry or style immediately after for a thicker, fuller result.
