Kumi Hair Growth Serum is a lightweight, leave-in scalp treatment designed to support healthier-looking, fuller hair over time. Instead of focusing only on the strands, this formula is applied directly to the scalp, where hair growth begins.

Each bottle features a precision brush applicator that allows you to deliver the serum exactly along the part line, crown, or hairline. The soft bristles help distribute the formula evenly while gently massaging the scalp, encouraging consistent contact where it matters most.

The serum absorbs quickly without leaving a heavy or greasy finish, making it suitable for daily use. It layers easily into your existing routine, whether applied at night or during the day before styling. With continued, consistent application, the scalp environment can feel more balanced and supported, and hair may appear thicker and more resilient.

This is not a quick fix. Hair density changes gradually, and visible improvement depends on regular use over time. Kumi is designed to make that consistency realistic, simple, and manageable.

Suitable for most hair types, including color-treated hair. Always perform a patch test if you have sensitive skin.
