About the product

Grow Perfect™ Thickening Spray is a refreshing, leave-in scalp treatment that functions as a lightweight hair thickening spray while also helping support healthier-looking density over time. Used after showering, this ultra-light formula soothes the scalp, boosts hydration, and creates an ideal foundation for fuller, stronger hair. With its blend of botanical extracts and clinically studied actives, this hair thickening spray is especially suitable for fine, flat, or thinning hair.

The formula features RootBioTec™, a basil root extract clinically shown to help reduce hair loss by up to 31% after two months¹. It works by helping limit the formation of DHT in the follicle through reduced 5α-reductase II activity, supporting stronger, more resilient hair growth at the root as part of your daily scalp treatment routine.

Alongside its scalp-supporting benefits, Grow Perfect™ Thickening Spray provides soft root lift and instant volume, giving fine or flat hair a fuller appearance without heaviness. This 99.6% naturally derived hair thickening spray is completely free from synthetic fragrance, sulfates, silicones, parabens, and mineral oils.

How it works

Grow Perfect™ Thickening Spray supports fuller-looking hair through three targeted mechanisms: soothing and hydrating the scalp, strengthening the follicle environment, and delivering instant lightweight volume. As a daily scalp treatment, it helps maintain the ideal conditions for long-term density.

Soothing botanicals including organic aloe vera, oat kernel extract, glycerin, and cloudberry extract help hydrate the scalp and ease dryness or irritation. A calm, hydrated scalp forms the foundation for more resilient hair growth and improves the effectiveness of any scalp treatment routine.

Clinically supported actives further enhance these benefits. RootBioTec™ has demonstrated up to a 31% reduction in hair loss after two months¹ by helping reduce DHT formation and supporting the dermal papilla cells that regulate hair growth. Protectagen™, a plant-derived microprotein complex, helps support microcirculation and provides antioxidant protection, reinforcing the scalp barrier and improving follicle vitality². Organic rosemary and spearmint oils offer an invigorating boost, and rosemary oil has been clinically associated with improved hair density over time³.

Finally, this lightweight hair thickening spray adds instant lift at the roots, helping revive hair that appears flat or lifeless. With continued use, Grow Perfect™ Thickening Spray helps hair appear fuller, stronger, and more voluminous while supporting an overall healthier scalp environment.

¹ RootBioTec™ study: Ocimum basilicum hairy root extract demonstrated up to 31% reduction in hair loss after 2 months (Mibelle Biochemistry).
² Protectagen™: Marine microproteins shown to support microcirculation and strengthen scalp barrier function (Lucas Meyer Cosmetics).
³ Rosemary oil study: Improved hair density similarly to 2% minoxidil after six months and reduced shedding (Panahi et al., 2015).
