What are healthy hair follicles?

Every hair on your scalp grows from a remarkable biological structure known as the hair follicle. Far from being a simple tube that produces hair, the follicle is a highly active mini-organ containing specialised cells. These cells constantly communicate with one another through chemical signalling molecules known as growth factors.

At the base of every healthy follicle lies a small but incredibly important structure called the dermal papilla. This cluster of specialised cells acts as the follicle’s biological control centre, helping regulate hair growth, blood supply, and communication with surrounding stem cells. When the follicle is functioning normally, these signalling pathways allow each hair to repeatedly pass through a healthy cycle of growth, transition, and rest.

However, when the environment surrounding the follicle becomes disrupted—whether through genetics, hormones, ageing, inflammation, stress, or other biological influences—the follicle may gradually become less efficient. Hair can become finer, grow more slowly, spend longer in its resting phase, or shed more readily.

Rather than replacing hair follicles, treatments such as PRP aim to support the follicle’s natural biological environment by delivering a concentrated source of your own naturally occurring growth factors directly to the scalp. These signalling molecules help create conditions that may encourage viable follicles to function more effectively and remain in the active growth phase for longer.

At Rejuvena, this understanding of hair biology forms the foundation of every treatment programme. We believe that successful hair restoration is not simply about performing injections—it’s about supporting the health of the hair follicle itself.
