How to fill in gaps in the eyebrows?

Semi-permanent makeup, similar to a brow tattoo , is increasingly being chosen when it comes to sparse eyebrows. It involves placing pigments into the epidermis to give an impression of density to the eyebrow. It's worth noting that this technique does not require the removal of existing hairs, as the design can be done beneath the hairs. Unlike permanent eyebrow tattoos, this type of procedure gives a fairly natural result. There are several methods of semi-permanent makeup, the two most common being the microblading and the microshading.

• Microblading : this technique involves pigmenting the epidermis using a needle to mimic eyebrow hairs. This procedure is usually carried out in two sessions spaced a few weeks apart. You can maintain the result for approximately a year and a half without needing any additional touch-ups.

• The microshading : This is a technique similar to microblading, the aim of which is to create a shading effect behind the eyebrows. It is generally better tolerated by sensitive skin because, instead of drawing lines to mimic hairs, only small dots are made.

A more radical solution, eyebrow transplantation is another method to fill in eyebrow gaps. This is a surgical procedure that may require several sessions lasting from 30 minutes to 3 hours. Eyebrow transplantation involves the removal of hair follicles located at the back of the head and their transplantation into the eyebrow areas where regrowth is desired. This operation must be carried out by a professional, as it is very difficult to alter the results obtained. Therefore, it is essential that it is performed correctly.

To naturally eliminate a gap in the eyebrows or to reshape them, it is also possible to rely on a natural approach. To strengthen the hairs of your eyebrows, you can opt for a nourishing vegetable oil, of which the castor oil is the most commonly used. By fortifying the eyebrow hairs, these vegetable oils ensure better health, and healthy hairs tend to grow faster. However, it cannot be definitively stated that these oils accelerate the growth of eyebrows.

Indeed, the belief that castor oil stimulates eyebrow growth stems from studies based on its action against alopecia, or hair loss. In these studies, it was shown that ricinoleic acid present in castor oil had an inhibitory effect on prostaglandin D2 (PGD2). Notably, this protein is approximately three times more prevalent in bald areas of the scalp than in hair-bearing areas.

She and her 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 demonstrated the ability of castor oil to stimulate it, which is why we can only assert that this vegetable oil contributes to the strengthening of hair.
