Soapbox Lengthening Vitamin Hair Booster 2-Pack — 5-Minute Lightweight Treatment with Biotin & Vegan Collagen

Soapbox Oh My Growth Lengthening Vitamin Booster is a lightweight, 5‑minute rinse-out treatment formulated with biotin, vegan collagen and vitamin C to leave hair looking thicker, fuller and more resilient.

This treatment is designed as a quick booster you can add to your routine when you want visible fullness and improved manageability without heavy buildup. The formula targets the appearance of density and helps protect strands from breakage while keeping natural movement and shine. Because it rinses out, the treatment works as a fast finish step after cleansing for an immediate thicker look and softer feel.

How quickly will I notice fuller-looking hair?

Results are intended to be visible after a single five-minute application; the product works on the surface to plump and smooth strands for a denser appearance. Repeated use supports stronger-looking hair over time thanks to biotin and vegan collagen in the formula.

• Apply after shampoo and leave on for five minutes before rinsing
• Visible fullness and softer texture after the first use
• Continued use helps maintain the appearance of thicker, healthier hair

Will this weigh my hair down or affect styling?

Soapbox formulated the booster to be lightweight so it adds volume without heaviness. It improves manageability and retains natural bounce, making it compatible with regular styling routines and heat tools when used as directed.

• Rinse-out treatment avoids residue that flattens hair
• Softens strands for easier detangling and styling
• Designed for daily or weekly use depending on desired effect

What key ingredients are included and what do they do?

The main actives include biotin, vegan collagen and vitamin C, chosen to support the look and feel of fuller, stronger hair. These ingredients work together to reinforce strand resilience and enhance surface texture without heavy oils or silicones.

• Biotin: supports the appearance of stronger, less breakage-prone hair
