Hair can stop growing or grow slowly for a variety of reasons including age, genetics, hormones, or stress. You may notice your hair stops growing in one spot or seems to be growing slowly on one side. There are plenty of treatment options for slow-growing hair, including: medication.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
One of the most important causes of restricted hair growth and hair thinning is nutritional deficiency. Nutrients like iron, protein, biotin and zinc contribute to healthy hair. However, if you are deficient in these essential nutrients, your risk of restricted hair growth and hair thinning increases.

Genetics
You might be surprised to learn that your hair doesn't actually stop growing at a certain length, it stops growing at the end of your hair growth cycle. Your hair's growth phase is determined by your genetics and can last anywhere between two and six years.
Many hair follicles stop producing new hairs. Men may start showing signs of baldness by the time they are 30 years old. Many men are nearly bald by age 60.
Androgens, such as testosterone (T), dihydrotestosterone (DHT), and their prohormones dehydroepiandrosterone sulfate (DHEAS) and androstenedione (A) are the key factors in the growth of terminal hair.
When vitamin B12 levels are low, your hair follicles may not be able to grow new hair as efficiently, resulting in hair loss. A vitamin B12 deficiency can also cause symptoms of anemia, which is associated with low iron levels, hair thinning, and hair loss.
If your hair loss is a result of nutrient deficiency, it's reasonable to expect that by reversing the deficiency, you may reverse the hair loss, or at the very least stop it in its tracks.

But some people with lupus develop round (discoid) lesions on the scalp. Because these discoid lesions scar your hair follicles, they do cause permanent hair loss. Lupus can also cause the scalp hair along your hairline to become fragile and break off easily, leaving you with a ragged appearance known as lupus hair.
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.
What are the most important factors influencing hair growth?
The levels of hormones that enable hair follicles to grow are decreased, and testosterone levels tend to increase, leading to the dominance of, again, DHT. As you can probably tell, sex, age, and subsequently, hormone levels are some of the most important factors influencing hair growth.
Hair growth rate slows at midlife and beyond—it spends less time in the growth phase and more in the resting phase, which means it will grow more slowly, and won't be able to grow as long as it once did.
How often should you trim your hair for maximum growth?
To maintain your length, aim for a trim every eight to ten weeks. If you are trying to grow your hair longer, you can get away with trimming your hair every 12 to 16 weeks. This however, is completely dependent on how healthy your hair is.
