It is often genetic, handed down from a parent, or it can be caused by hormonal factors such as menopause or childbirth, birth control pills or other medications, disease or illness, poor diet, stress, a fungal infection of the scalp or cancer treatments.
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.
Telogen hair, or 'resting' hair, comprises around 15% of the hair on a person's scalp. Periods of elevated stress can lead to this hair being temporarily lost, contributing to a visibly thinner scalp and hairline.
However, vitamin B12 may give you the appearance of fuller and thicker hair because the increase in oxygen to hair follicles can help stimulate the replacement of lost strands. Vitamin B12 may also help give your hair an overall healthier appearance since intake of enough B12 is responsible for stronger hair shafts.
Whether you are trying to avoid chemicals or are just looking to experiment with some new hair care products, try natural oils such as coconut, argan, jojoba, almond, olive and grapeseed. These are some of the best oils for hair health and can be used directly on the skin and hair.
If you have thin hair, a blunt cut will feign thickness, and a pixie cut makes those strands feather-light and much more pliable for styling. For thicker fine hair, well-placed long layers give dimension and volume to your bobs and lobs.
Water is a key ingredient that supports vitamins, which contribute to your hair growth. Believe it or not, but water makes up almost 25% of the weight of a single strand of hair. Drinking at least two liters of water a day will help the strength of your hair, increasing growth.
Certain styles—like bobs and blunt cuts—can actually create the illusion that your hair is thicker than it is. "Short hairstyles are best for thinning hair, because too much length can drag the hair down and create an unflattering, stringy appearance," says Alabama stylist Hope Russo.
As with male pattern baldness, female pattern baldness comes from hormone imbalances, specifically dihydrotestosterone imbalances, or DHT. This hormone is similar in structure to testosterone, but it is significantly more potent [3]. DHT can attach to receptors on the hair follicles, causing the follicles to shrink.
Hair thinning causes can include aging, your genes, shifting hormones, and your diet. Learn what else might be playing a role. Whether you're a woman or a man, it's normal for your hair to thin as you get older, according to Cleveland Clinic.
Sandalwood, lavender, rosemary, and thyme oils have been used to treat hair loss for over 100 years. A compound in them is thought to boost hair growth. You can try rubbing one or more of these oils into your scalp for at least 2 minutes every night.
"Ironically, with thinning hair it's important to make sure you get your hair cut regularly," says Julie Hensman, from Hensmans in Northampton. "Thinning hair can get out of shape more quickly, making it look more obvious". Booking in for regular trims can keep your hair looking its best.
