Hair Loss: Types of Alopecia and Causes of Thinning Hair
Table Of Content
The follicle is lined by an inner and outer sheath that protects and molds the growing hair. The inner sheath follows the hair and ends just before the opening of the oil gland, or sebaceous gland. The outer sheath continues all the way up to the gland. The bulb is the rounded structure deep in the skin at the root of the hair that surrounds the papilla and germinal matrix.
The hair care-health connection
“When you have had your hair in a protective style for weeks, the curl formation is completely gone. The cuticle is so dry and open that it becomes like little fish hooks that catch on each other and break when you take out the braids,” Castillo said. The natural state of type 2 hair is a gentle, tousled texture. From the roots to around eye level, your hair is fairly straight.

Instead of combing, which can lead to frizz and breakage, use a leave-in conditioner and rake through wet hair with your fingertips. The American Academy of Dermatology recommends that you air-dry instead of using a blow dryer.
How Hair Forms
Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. The first to develop is the lanugo, a layer of downy, slender hairs that begin growing in the third or fourth month of fetal life and are entirely shed either before or shortly after birth. During the first few months of infancy there grow fine, short, unpigmented hairs called down hair, or vellus.
How to Identify and Style Your Hair Type
The amount of melanin typically decreases as people get older, and more air gets trapped inside the hair – it then loses its color and turns white. Depending on someone’s original hair color and the number of white hairs that grow, the hair on their head then turns gray or white. The shaft is the visible part of the hair that sticks out of the skin. The hair root is in the skin and extends down to the deeper layers of the skin.
These hairs then form a heat-trapping layer above the epidermis. The opposite actions occur when the body is too warm; the arrector muscles make the hair lie flat on the skin which allows heat to leave. Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals.The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair.
Some religious groups may follow certain rules regarding hair as part of religious observance. Laser hair removal is a cosmetic method where a small laser beam pulses selective heat on dark target matter in the area that causes hair growth without harming the skin tissue. This process is repeated several times over the course of many months to a couple of years with hair regrowing less frequently until it finally stops; this is used as a more permanent solution to waxing or shaving. Laser removal is practiced in many clinics along with many at-home products.
Though some stylists swear by styles that allow you to tuck away fragile ends to protect them while they grow out, Castillo says these styles often do more harm than good. While the hair is out of sight, it’s also out of reach for conditioning treatments. That hair loss happens because the weight of the ponytail pulls against the front of the hair for prolonged periods. Type 2B is ideal for the balayage trend, where stylists hand-paint color on the outer layer of hair. To keep from flattening out that wave, steer clear of oil-based or creamy products. Instead, stylists recommend that you boost the base with a light mousse or use a gel to define those waves.
The full strand of hair develops from this group of hardened hair cells. Because new hardened cells keep on attaching to the hair from below, it is gradually pushed up out of the skin. In this way, a single hair on your head grows at a rate of about 1 cm per month.
The arrector pili muscle, a tiny bundle of muscle fiber, is attached to the outer sheath. When the muscle contracts, it causes the hair to stand up, otherwise known as goosebumps. This article gives an overview of the structure of hair. It explains how it grows, what it’s made of, and how it changes. More than 60 percent of the women who participated in the study wore their hair in a chemically relaxed style. It may morph the moment you step out into actual weather.
Washing your hair too often can cause your scalp to overproduce oils, so dry shampoo is a boon for people with straight, oily hair. Stylist Kristi Lovelace also suggests avoiding heavy serums or butters. “With straight or fine hair, I’d recommend texture sprays instead. At the base of the hair, the hair root widens to a round hair bulb. The hair papilla, which supplies the hair root with blood, is found inside the bottom of the hair bulb.
The eyebrows provide moderate protection to the eyes from dirt, sweat and rain. They also play a key role in non-verbal communication by displaying emotions such as sadness, anger, surprise and excitement. In many other mammals, they contain much longer, whisker-like hairs that act as tactile sensors. Hair grows everywhere on the external body except for mucus membranes and glabrous skin, such as that found on the palms of the hands, soles of the feet, and lips. It’s a good idea to take stock of the products you’re using if your hair density has changed.
In early modern China, the queue was a male hairstyle in which the hair at the front and top was shaved every 10 days in a style mimicking pattern baldness, while the remaining hair at the back was braided into a long pigtail. Jablonski's assertions[52] suggest that the adjective "woolly" in reference to Afro-hair is a misnomer in connoting the high heat insulation derivable from the true wool of sheep. Further, wet Afro-hair does not stick to the neck and scalp unless totally drenched and instead tends to retain its basic springy puffiness because it less easily responds to moisture and sweat than straight hair does.
The individual strands may be fine or coarse, thick or thin, but they fall without waving from root to tip. You could have type 4C at your crown and 4A at your temples. Your hair could be straight at the root and wavy at the ends. The key is to understand what each type needs so you can style it well and keep it healthy. Waxing involves using a sticky wax and strip of paper or cloth to pull hair from the root.
This argument assumes that curly hair better impedes the passage of UV light into the body relative to straight hair (thus curly or coiled hair would be particularly advantageous for light-skinned hominids living at the equator). The rate of hair loss may increase noticeably if the hair roots are damaged during the growth phase or if a lot of hairs go into the resting phase at the same time. If no new hair grows and replaces the hair, that part of the skin becomes bald. This type of hair loss is referred to as alopecia – regardless of how large the bald spot is or whether it affects the scalp or body hair.
If you’re not sure where to start, consult a professional who specializes in your type of hair, or follow someone with your hair type on social media. Look for texture sprays and light mousses to add volume and lift. High density hair can benefit from thicker creams and butters to add shine and control. Hair density refers to the number of hairs on your head. If you can’t see your scalp clearly, you probably have dense hair. If you can see your scalp even without parting your hair, you probably have low hair density.
