The use of avocado oil on nails.

Nails are a crucial component of the fingers and serve multiple functions. Beyond their aesthetic appeal, nails contribute to the hygiene of the hand and foot, as well as their protection. This semi-transparent plate is primarily composed of keratin, a fibrous protein. Numerous mineral salts are also present within the nails, such as calcium, sodium, magnesium, or iron. Nails are a relatively delicate part of the body and subject to numerous concerns.

• The white spots on the nails: they are generally due to a shock or a slight trauma to the nail. Too frequent manicures or pedicures or the regular use of acetone can also be the cause.

• Dark streaks on the nails: they are often related to a haematoma, which occurs after a shock, when the blood vessels under the nail are damaged and burst.

• A yellow hue of the nails: nail polish tends to cause a slight yellowing of the nails. Similarly, certain fungal conditions or smoking can promote this phenomenon.

• Horizontal stripes on the nails: these appear when the growth of the nail has decreased or has been stopped for some time. An injury or minor ailment could be responsible.

• Small holes on the nails: they are generally associated with psoriasis, a skin disease that leads to the formation of red, dry, and scaly patches on the elbows, knees, and other parts of the body.

• The detachment of keratin plates : nails are highly porous and sensitive to water, which can cause the keratin plates to swell and detach from each other. The nails then become soft and start to split.

• Brittle nails : this is a common issue that can be attributed to the natural ageing of the nail, but also to prolonged exposure to detergents or nail varnishes. These compounds are likely to attack and deteriorate the top layer of the nail, causing it to become brittle. Nails can also be weakened by a deficiency in iron, zinc or vitamin B, elements that stimulate the synthesis of keratin. Finally, hormonal drops experienced by women after childbirth or during menopause can also make nails more brittle.
