Scalp Stem Cell

01. Many Signals. One Strand. Scalp Stem Cell

Many Signals. One Strand.

Hair seems simply to grow longer. But beneath the skin, countless signals guide its cycle of growth, rest, and renewal. Follow those signals, and you arrive at the base of the follicle: the dermal papilla. Small and unseen, it is closely involved in hair growth. The world beneath each strand is more intricate than it appears.

02. A Small Structure Behind Every Strand

A Small Structure Behind Every Strand

The dermal papilla does more than receive nutrients. It sends signals involved in growth and regression to the surrounding hair matrix cells, while a network of fine capillaries supplies it with oxygen and nutrients. Signals pass. Cells respond. Hair grows again. Beneath the strands we see every day, this quiet rhythm continues.

03. Before Hair Disappears, It Becomes Finer

Before Hair Disappears, It Becomes Finer

Hair loss does not always begin with an empty space. Once-thick strands gradually become finer and weaker. Eventually, more light reaches the scalp along the part. This is miniaturization: the progressive thinning of individual hairs. The thickness of each strand becomes as important as the number of hairs. Our attention naturally turns to where those strands are formed.

04. The Answer Lies Beneath the Hair

The Answer Lies Beneath the Hair

Hair is formed beneath the skin, around the dermal papilla at the base of the follicle, approximately 2–4 mm below the surface. Stem cell scalp treatments use cells derived from the patient’s own body around the follicles to support the environment of the hair roots and follicular cells, helping promote healthy hair growth. The focus is on the conditions for hair yet to grow. At Page Lab, autologous stem cells obtained through EXOSMART are applied to the scalp.

05. Fullness Develops Strand by Strand

Fullness Develops Strand by Strand

Hair grows in its own time. Changes therefore tend to appear first in small details. The thickness of a strand. The width of the part. The light reaching the scalp at the crown. Each difference is subtle. Together, they change the overall impression of the hair. The appearance of fullness begins with a single strand.
