Why hair needs regular deep nourishment

Introduction: Hair nutrition, the foundation of healthy hair

Hair, like skin, is constantly exposed to harmful factors. Sun, pollution, stress, coloring, tight hairstyles... All these factors weaken the hair fiber and deplete its natural nutrient reserves. Shiny, strong hair cannot exist without regular, appropriate nutrition. As a trichologist, I can explain why deeply nourishing your hair is essential to its vitality.

1. Understanding hair structure to nourish it better

Hair is composed of 95% keratin, an essential protein produced from amino acids and vitamins provided by diet and topical care. On the surface, the cuticle protects the inner cortex, but this barrier can deteriorate under the effect of external aggressions. The result: hair becomes porous, dull, and brittle. Deep nourishment restores this structure to ensure strength and suppleness.

2. The consequences of poorly nourished hair

Hair that lacks nutrients is easy to recognize: it feels dry to the touch, loses its shine, breaks easily, and may even grow more slowly. This phenomenon is particularly pronounced after exposure to the sun, chlorine, heated styling tools, or repeated chemical treatments. Without a regular supply of lipids and vitamins, the hair fiber becomes irreparably fragile.

3. The benefits of nourishing vegetable oils

Certain vegetable oils have the ability to penetrate the hair fiber to repair it from within. Among the most effective are:

• Castor oil : fortifying and thick, it intensely nourishes damaged hair.

• Rice bran oil : rich in antioxidants, it regenerates and protects.

• Jojoba oil : light, it moisturizes without weighing down the skin and regulates sebum.

Applied in an oil bath once or twice a week, these oils restore suppleness, reduce breakage, and prolong the life of the hair.

4. The importance of the scalp in hair nutrition

A healthy scalp is the foundation of effective hair nutrition. By stimulating microcirculation through massage, you promote the supply of nutrients to the follicles. A well-nourished scalp produces thicker, shinier, stronger hair.

5. How to incorporate nutrition into your routine

• Oil bath : leave on for 1 hour or overnight.

• Gentle shampoo : sulfate-free, so as not to strip away the protective barrier.

• Nourishing leave-in treatment : made from vegetable oils or butters.

• Targeted serum : to seal in moisture and strengthen the ends.

Conclusion: nourished hair is hair that lasts a long time.

Never overlook the nutritional benefits of your hair care products. Providing your hair with the right nutrients at the right time ensures its longevity, shine, and resistance to daily damage.
