How Do Hair Growth Supplements Work?

Supplements known as hair vitamins claim to have positive effects on the health of the hair. well-known businesses promote their products as having the ability to boost hair thickness, strength, shine, and growth. There are several products on the market, and many of them contain identical ingredients like biotin, vitamins C and E, collagen, folic acid, and omega-3 fatty acids. It may also contain the supplements ginseng and ashwagandha, which some believe can thicken hair.

Which Nutrients Are Good For Hair?

Age, genetics, hormone levels, medical issues, food, stress, and hair treatments are just a few of the many variables that affect hair health. This makes it challenging to identify the primary cause or sources of any problems. Evident hair thinning or loss, a lack of growth, dryness, fragility, brittleness, and dullness are all symptoms of unhealthy hair. It’s often possible to support healthy hair by altering your food and lifestyle.

More specifically, consuming enough of these essential nutrients may enhance the strength and health of your hair. Protein, biotin (B7), iron, selenium, zinc, vitamin A, vitamin b12, vitamin c, vitamin d, vitamin e. Being the primary component of hair, protein is very important for hair growth. Furthermore, nutrient shortages such as those in B vitamins, iron, and vitamins C and D have been related to hair loss, weak hair development, and thinning hair. Extremely low-calorie and fat diets, such as some weight reduction regimens, as well as diets that exclude entire food groups, like vegan eating habits, can also result in increased hair loss and weak, unhealthy hair.

vitamin E nourishes and shields the skin, hair, and nails from UV damage. Fruits, vegetables, nuts, seeds, and vegetable oils derived from plants are excellent sources of vitamin E.

DHT (dihydrotestosterone), a hormone that can result in hair loss, can be controlled by zinc levels in the body. DHT is a hormone that can lead to hair loss and is produced more when zinc levels are low. Zinc is found in abundance in fish, eggs, almonds, and sesame seeds.

The growth of hair requires iron. Hair loss is caused by the effects of low iron levels on the hair follicles and the disruption of the hair’s growth cycle. Lentils, red meat, spinach, and green vegetables are among the foods high in iron.

To help collagen develop, vitamin C functions as an antioxidant. Iron absorption is aided by vitamin C as well. Oranges, sweet potatoes, kiwis, and other citrus fruits are excellent sources of vitamin C.

When hair follicles are produced in a healthy state, hair growth is encouraged. Stress and despair are also lessened by vitamin D. Oily fish, mushrooms, and eggs all contain it.

Sebum, a natural oil that keeps the skin and scalp moisturized and healthy, is formed with the aid of vitamin A. The scalp becomes dry, inflamed, itchy, and flaky as a result of a reduction in sebum brought on by a vitamin A deficiency. The hair also becomes brittle, dry, and prone to breaking as a result. The fact that excessive vitamin A consumption can also result in hair loss must be kept in mind. Yellow or orange foods, such as carrots, contain vitamin A.

The growth of healthy hair depends on amino acids. Keratin, a protein that supports and improves the texture of hair and encourages hair growth, is made possible by amino acids. In foods like dairy, beef, and eggs, amino acids the building blocks of proteins can be found.


The ability of hair vitamins and supplements to treat hair issues is not well supported by clinical research, despite their widespread use. While some nutrients have been associated with greater hair health, the majority of research has demonstrated that hair supplements are only useful for persons whose hair problems are brought on by an existing nutrient shortage.

How Long Do The Supplements Need To Work

Results do not appear right away when taking the best vitamins for hair growth. In most cases, noticeable hair growth doesn’t happen for a very long period. Even after taking supplements, it would still take five to six years for a new hair strand to reach shoulder length because hair normally grows at a rate of only half an inch each month.

The hair can also be seen to have undergone several additional alterations. Supplement use for a few months causes the oil glands on the scalp to reawaken, which hydrates and feeds the hair and scalp. The appearance of the hair starts to become healthier, shinier, and more moisturized. The likelihood of hair breakage may be lower due to the hair’s potential for less brittleness.

Causes Of Hair Loss

There are many factors


Age causes a slowdown in hair growth that eventually leads to hair follicles ceasing to produce hair. The color and density of hair are also impacted by aging. According to the study, each person’s hair follicles begin to reduce their production at a different age. It can be 40 years old for some and 70 years old for others.


From affecting collagen formation to causing acne and, yes, hair loss, hormones have a significant impact on appearance. The stress hormone cortisol, which we’ll discuss in more detail in the following section, is one of the key hormones that affect hair, although thyroid and sex hormones also have an impact on hair development. For instance, because keratin production and estrogen are both correlated, pregnant women may have luscious, thick hair that loses soon after giving birth.


Stress and hair loss are proven to be related in numerous studies. This comes back to the idea of balance, or homeostasis, in the body, particularly regarding the sympathetic nervous system and the adrenal glands. Both of these hormones if out of balance owing to high stress would induce hair thinning and loss.
