Androgenetic alopecia – in women, hair generally thins in the top, frontal area, just behind the hair line, but stays thick at the back. An enzyme causes conversion of the male sex hormone testosterone to another hormone, dihydrotestosterone (DHT), causing the hair follicles to produce thinner hair until they stop.
That might be eczema, psoriasis, or a condition called frontal fibrosing alopecia, which typically causes scarring and hair loss — sometimes permanent — at the front of the scalp above the forehead.
Here's the truth: You can't change the size of your hair follicles. If you were born with fine hair, it's genetics, and no product will completely alter that. Of course, there are ways to maintain your hair health, add volume, and keep it from getting any thinner.
If the reason for thinning hair is genetics, it will not grow back on its own. To grow back a healthy, full head of hair, you'll need to take action, and that involves reviewing different hair loss options.
Can you increase hair density? Like many other aspects of hair — like its color and texture — hair density is determined by genetics. Your hair grows out of a part of your skin called a hair follicle. You can't change the number of hair follicles you have.
More than 90% of Han Chinese, 70% of Japanese and Thai people, and 60% to 90% of Native Americans carry the “thick hair" version of the gene. Meanwhile it's almost nonexistent in people of African and European descent.
Vitamin C
Vitamin C is also of the top vitamins for thicker fuller hair because it's critical for the body's production of collagen, an essential ingredient in the hair structure. Foods such as red bell peppers, dark leafy greens, tomatoes and citrus fruits are rich in Vitamin C.
When hair starts to regrow, it appears like fine “peach fuzz.” It is usually translucent and thinner than the rest of the hair on your scalp. If you recently underwent surgery or had a head injury and are worried about hair growth on the bald spot, the appearance of peach fuzz is a positive sign.
Whipping wind can suck the moisture from your strands, leaving them brittle and dry. This can also lead to damage to the cuticle—the outermost layer of your hair—which opens the door for deeper damage to the cortex, or inner protein-rich segment of your hair.
Whether your hair is thick or thin, curly or straight, gusts of wind are going to sap your hair of moisture, too. Increased friction is going to wear away at the cuticle and create damage.
Fine hair describes your hair's texture, which is classified in terms of the width, diameter or circumference of the actual hair strands. If you have fine hair, your individual strands are smaller in diameter, while coarse hair has a thicker diameter.
Common causes include aging, changes in hormone levels, heredity, medications, and medical conditions. It's important to see a doctor if your hair loss is sudden, or if you suspect it's caused by an underlying medical condition.
“Thinning along the hairline or temples is more than likely the result of either traction alopecia, excessive hairstyling habits, genetic hair loss, or frontal fibrosing, which is a form of lichen planopilaris, an autoimmune disease that triggers scarring alopecia,” she explains.
Hair loss in your 20s and 30s
Few people expect hair loss to happen as early as their 20s or 30s. But the good news is hair loss during these decades is usually caused by a specific trigger that, when addressed, will likely stop the hair loss. Three of the most common triggers are stress, dieting, and hormonal changes.
Your hairdresser may advise you that shaving your head if your hair is thinning isn't necessary yet, and instead will cut your hair into a style that accommodates your thinning hair better.
Strengthens and thickens: Biotin "is well known for its positive effects on hair including growing stronger thicker strands," says Friese. Protects: Because biotin strengthens hair, it is less likely to break off at the ends, promoting and protecting length, explains Friese.
