It's not uncommon to be a bit heavy-handed when plucking one's eyebrows. We quickly regret it afterwards and wish they would grow back as quickly as possible. But how can this be achieved? Here are some tips to stimulate the growth of your eyebrows.
The life cycle of eyebrows.
Just like hair, eyebrow hairs grow approximately 0.3 millimetres per day. However, the duration of their growth cycle differs. Indeed, it is estimated that eyebrows grow for about 30 days, whereas the growth phase of hair lasts from 2 to 5 years. This is why hair is much longer than eyebrows. The life cycle of eyebrows lasts about 4 months. It is similar to that of hair and is characterised by the following stages:
The anagen phase : during the growth phase of an eyebrow hair, the cells at its root actively multiply, leading to an increase in its length.
The catagen phase : This is a resting phase during which eyebrow growth ceases. This period can last from a few weeks to a few months. During this time, the eyebrows remain in place without undergoing significant changes.
The telogen phase : The telogen phase is the shedding stage of the eyebrows. They naturally fall out to make way for new hairs, growing from the hair follicles.
Note : An eyebrow can house up to 1,000 hairs, each with life cycles independent of one another. This is why the overall density of our eyebrows remains the same over time.
Tips to stimulate the growth of one's eyebrows?
Overzealous hair removal, an injury to the eyebrow that leaves a gap... these are all reasons to want to stimulate eyebrow growth. First and foremost, it's important to note that while certain tips can somewhat stimulate eyebrow growth, they will not, however, be able to thicken your eyebrow line. This is unique to each individual and depends on the number and location of hair follicles present within your eyebrow arch.
A diet that is healthy and rich in nutrients.
Diet plays a significant role in our well-being and health. It also influences the growth of our eyebrows. Indeed, a nutrient-rich diet, including vitamin B, magnesium, and iron, can strengthen hair follicles and thus indirectly stimulate eyebrow growth. These nutrients are particularly found in whole grains, legumes, certain meats, and some fish.
Using certain active ingredients.
Some active ingredients are capable of stimulating the growth of hair follicles (eyelashes, eyebrows, hair). These include, for example, biotinyl-GHK and panthenol, derivatives of vitamin B. These actives work at several levels to strengthen the eyebrows and stimulate their growth. They first strengthen their anchorage by increasing the synthesis of laminin 5 and type IV collagen. These two adhesion proteins make up the basal membrane that separates the epidermis and the dermis.
Furthermore, biotinyl-GHK and panthenol promote the proliferation of keratinocytes in the hair follicle. To do this, they stimulate the activity of the Ki-67 protein which intensifies cell proliferation. They therefore have a positive effect on eyebrow growth.
Applying plant-based oils.
Applying certain nourishing plant oils to the eyebrows can strengthen and hydrate the hairs. Healthy hairs, in turn, grow more quickly. Among the most popular are theavocado oil, thecoconut oil, and especially thecastor oil. The latter is attributed with the ability to stimulate eyebrow growth due to scientific studies based on its action against alopecia, or hair loss.
Indeed, during these studies, it was demonstrated that the ricinoleic acid found in castor oil had an inhibitory effect on Prostaglandin D2 (PGD2). It is observed that this protein is approximately three times more prevalent in bald areas of the scalp than in hair-bearing areas. It and its metabolite 15-dPGJ2 interrupt hair growth by binding to the GPR44 molecular receptor. By inhibiting Prostaglandin D2, castor oil restores hair growth. Regarding eyebrow growth, however, no study has yet shown the ability of castor oil to stimulate it, which is why we can only assert that this vegetable oil contributes to the strengthening of the hairs.
As previously mentioned, healthy eyebrows tend to grow more. Therefore, it is important to take care of them. To do this, you can perform a scrub once a week. This treatment helps to rid the skin under the hairs of dead cells and reduce the risk of ingrown hairs. In addition to the scrub, the regular application of a strengthening serum is recommended. You might, for instance, consider our eyelash and eyebrow serum. Concentrated in pea peptides (INCI: Pisum Sativum (Pea) Peptide) and castor oil (INCI: Ricinus Communis (Castor) Seed Oil), nourishing and densifying active ingredients, our serum strengthens and fortifies eyelashes and eyebrows. It can be applied morning and evening and does not need to be removed with a makeup remover.
Finally, the last piece of advice to keep in mind is to be patient. Eyebrows have their own life cycle that it is important to respect. This natural process takes time but eventually leads to the growth/regrowth of the eyebrows.
