Oils don't inherently make hair thicker in the sense of increasing the number of hair follicles. Instead, oil promotes a healthier scalp and hair shaft, leading to fuller-looking hair and stimulating growth.
Here's how:
-
Stimulates Blood Circulation: Massaging oil into the scalp increases blood flow to the hair follicles. This enhanced circulation delivers more nutrients to the follicles, supporting healthy hair growth.
-
Nourishes the Scalp: Oils are rich in vitamins, minerals, and fatty acids that nourish the scalp. A healthy scalp is crucial for healthy hair growth.
-
Strengthens Hair: Some oils penetrate the hair shaft, reducing protein loss and strengthening the hair from the inside out. This helps prevent breakage, making hair appear thicker and fuller.
-
Reduces Breakage: By lubricating the hair shaft, oils reduce friction and prevent breakage, a major cause of thin-looking hair.
-
Adds Shine and Moisture: Oils coat the hair shaft, adding shine and locking in moisture. This makes hair appear healthier, smoother, and more voluminous.
In short, while oil can't change the density of hair follicles, it creates an optimal environment for hair growth, strengthens existing strands, and improves overall hair health, all contributing to the perception of thicker, fuller hair.
