Certain factors like biological or premature aging, oxidative stress, hormonal imbalance, nutritional deficiency, and inflammatory damage reduce melanin production in follicles, causing greying.

Smoking, stress, UV exposure, lack of sleep, and environmental pollution increase oxidative stress, while the use of certain chemicals, heat styling, and other treatments weaken melanocytes, reducing pigment.

Chemicals like ammonia, hydrogen peroxide, and toxins accelerate oxidative stress, damaging melanocytes. To penetrate the cuticle and deposit color, they break hair proteins, bleach existing natural pigment, and weaken the shaft. Some chemicals also cause scalp inflammation, further affecting the roots.

Henna & indigo, natural sources of red and blue pigments, bond with keratin without breaking the cuticle due to henna's natural keratin-binding tendency. Henna leaves a red pigment, allowing indigo to bind and create a dark/black color. The herbs in both pastes enhance staining, binding, and provide benefits like melanin promotion and conditioning.
