The Hair Renewal Serum brings the two core CU Glow actives GHK-Cu and exo³ to the scalp and follicular environment. GHK-Cu supports the appearance of a healthy follicular cycle. exo³ supports the scalp's natural cellular communication, which underpins the look of density and strand resilience. Used twice daily for sixty days, most users notice a visible improvement in the appearance of density and a reduction in the appearance of thinning at the crown and temples. The Serum is lightweight, absorbs fully without residue, and does not affect hair styling.

Apply four to six drops directly to a dry or towel-dried scalp using the glass dropper. Part the hair in sections for even coverage. Massage gently with fingertips for sixty seconds. Do not rinse. Style as usual.

Use morning and evening for sixty days minimum before evaluating results.
