An emerging area of haircare research is exploring how the scalp microbiome (yes, just like our gut and skin, our scalp has its own community of microorganisms) may influence hair loss. Caroline Bertrand, Sisley’s head of active department and scientific communications, explains, “The scalp microbiome is a collection of living microorganisms similar to those found on the skin or in the gut.” According to Bertrand, an imbalance in these microorganisms, particularly involving two specific bacteria, can trigger inflammation that may contribute to hair loss.
Good habits for caring for your hair
So, how can we maintain a healthy balance of microorganisms on the scalp? According to Florence Maraval, brand director of Hair Rituel by Sisley, it begins with choosing the right haircare products. “We must be careful to choose shampoos that aren’t harsh because the microbiota contains living microorganisms and if products don’t respect them, they’re destroyed and the balance is disrupted. The key is to use formulas with mild surfactants like betaines. They produce less lather but are very effective,” she explains.
Other recommended habits include following an anti-inflammatory diet, protecting your hair from sun exposure and avoiding direct heat from a hair dryer on the scalp. Maraval also highlights the benefits of scalp massage, particularly for stimulating circulation and easing stress.
“The scalp is highly vascularised; it has an extensive microcirculatory network. If the massage is performed correctly, it stimulates that microcirculation, which helps the applied products penetrate better and be absorbed more effectively. Additionally, it reduces cortisol levels and helps alleviate stress. This also promotes better absorption of the active ingredients.”
As for the technique, Maraval recommends using the entire surface of your fingertips to gently move the scalp over the skull in soft, circular motions. The idea is to lift and move the skin rather than rub it or apply excessive pressure.
There is, however, one common misconception worth addressing: you cannot speed up the natural rate of hair growth. What you can potentially improve, Bertrand explains, is hair density, or the number of hairs per square centimetre, which can make hair appear fuller and thicker. “Hair growth depends on genetics and we can’t change that, but we can reactivate growth since some people have hair follicles that remain in a resting phase and just need a stimulus to become active again,” Bertrand concludes.
