Soapbox Oh My Growth Lengthening Vitamin Booster Rinse-Out Treatment with Biotin B7 & Vegan Collagen - 5 fl oz

Visible Fullness. Unbreakable Strength.

Give your hair a boost to reach the fullness you crave. This biotin and collagen hair treatment is a 5-minute rinse-out lengthening vitamin booster to give you hair that looks fuller, feels thicker, and supports stronger growth. In clinical testing, 82% saw more hair thickness, 85% saw less damage, and 91% said their hair felt healthier*. Oh My Growth blends biotin B7 to promote the appearance of fuller hair, vegan collagen to support healthier-looking strands, and an omega 3 blend to help improve visible hair thickness. We've also added banana and amla berry extracts to help prevent breakage, making this one of the most effective hair lengthening products you can add to your daily ritual.

Supercharged with a 5X Vitamin Complex

We didn't stop at biotin and collagen. This hair rinse out treatment is powered by a custom 5X vitamin complex designed to tackle multiple hair concerns in one step. Unlike typical hair strengthening products, these hair vitamins work together for total coverage: Vitamin B7 promotes the appearance of fuller hair, Vitamin B9 helps deliver visible shine, Vitamin B5 moisturizes strands, Vitamin C nourishes the scalp, and Vitamin E strengthens hair from within.

2 Ways to Use

You can target the scalp by applying directly after shampooing - run the precision tip along your scalp and massage from root to tip, leave on for 3–5 minutes, then rinse and follow with conditioner.

Or boost your conditioner by blending the treatment into your Soapbox conditioner after shampooing, applying as you normally would, leaving on for 3–5 minutes, and rinsing.

Use 3x a week or whenever you wash your hair.


Clean Ingredients You Can Feel Good About

Among hair volume products on the market, few match the clean standards Soapbox holds. Always vegan and cruelty-free, this hair vitamin booster is proven effective without the harsh chemicals that can strip or weigh hair down. It’s also dermatologist tested and hypoallergenic. Comes in a 5 fl oz bottle with a precision tip for easy, targeted application.
