eyebrow hair others describe hair quality.
Simple, one Is Vellus and the other is Terminal.
Vellus hair is fine peach fuzz found all over the body that is unpigmented, and does not stand up on its end (ie. goosebumps), whereas terminal hairs are thick, coarse and heavily pigmented. Terminals hairs have the capacity to stand up (goosebumps) and also contain sebaceous glands.
Adults of two kinds of hair: vellus and terminal. Vellus hair is short, fine, soft, and nonpigmented. Terminal hair is coarser, longer, thicker, and usually pigmented.
The scientific name for human body hair is "vellus hair" or "terminal hair", depending on the type and location of the hair on the body. Vellus hair is fine, short, and light-colored, while terminal hair is coarser, longer, and darker.
The different types of hair are VELLUS, LANUGO and TERMINAL. TERMINAL is coarse strong hair found in the pubic areas and on the head, eyebrows etc. VELLUS hair is fine short hairs found all over the body. LANUGO hair is found on unborn feutes' and is also fine and short. The different types of hair are VELLUS, LANUGO and TERMINAL. TERMINAL is coarse strong hair found in the pubic areas and on the head, eyebrows etc. VELLUS hair is fine short hairs found all over the body. LANUGO hair is found on unborn feutes' and is also fine and short.
The two types are ~ Vellus which is the soft hair that covers most of the body, and the Terminal which is the coarser hair on the head, eyes, pubic and axillary regions.
Vellus hair grows all over the body. It is the fine, light hair that covers the skin.
Vellus Hair
Vellus Hair
It's called vellus hair (blonde "peach fuzz") turning Into terminal hair. The vellus hair will first grow longer and will then start to turn dark brown hair and if he shaves the blonde hair, he lose it forever and dark brown hair will start to grow in those areas, if he doesn't shave, some of those hairs could remain partially blonde forever. Genetics has a big role in this
he growth of vellus hair and the secretion of sebum from vellus hair follicles were measured on the forehead, cheek, chest, shoulder and back of healthy men and women aged 15-30 years. Hair growth was assessed by computerized image-analysis of photographs and sebum excretion by the use of Sebutape followed by image analysis. The density of vellus hairs and the percentage of growing hairs were higher on the face than on the thorax (439 hairs/cm2 with 49% growing hairs on the forehead compared with 85 hairs/cm2 with 31.5% growing hairs on the back). The rate of growth ranged from 0.03 mm/day on the forehead to 0.13 mm/day on the back. The maximum length of vellus hair significantly decreased with age; otherwise hair growth was not affected by age or sex. Some variations in hair growth and sebum secretion were observed over a period of 3 months, but no consistent rhythms were detected. There was no obvious link between vellus hair growth and sebum excretion.
