What are keratinocytes?
Keratinocytes are the primary cells in the epidermis responsible for producing keratin, the structural protein found in hair, skin, and nails.
These cells also contribute to the skin’s barrier function and respond to inflammation, stress, and light stimuli. Healthy keratinocyte function is vital for scalp and follicle resilience.
Red light therapy can stimulate keratinocyte proliferation and function, aiding in the regeneration of scalp tissue and supporting healthy hair growth environments.
