Does Zinc Help in Hair Growth?

If you are experiencing thinning or excessive shedding of hairs, then there is probability that you might be having zinc deficiency. Individuals with zinc deficiency are more likely to experience excessive shedding of hair, thinning of the hair, and even complete hair loss in some cases. This is because zinc is essential for the proper growth and maintenance of hair follicles, and a lack of this mineral can disrupt the hair growth cycle, leading to increased hair fall and decreased hair density. Zinc supplements can help in hair growth by supporting cellular functions involved in the synthesis of DNA, RNA and proteins. All of which are essential for the growth and development of hair follicles by maintaining hormone levels and protecting against oxidative stress.

Zinc supplements definitely help in hair growth, particularly for individuals who are experiencing hair loss due to a zinc deficiency. It is essential for the growth and renewal of hair follicles, and a lack of this can lead to thinning, shedding and even bald patches. Zinc deficiency has been linked to different hair-related issues, including telogen effluvium (excessive hair shedding), alopecia (patchy hair loss), and poor hair quality. Zinc also helps to regulate hormone levels in the body, including those that affect hair growth. For example, it helps to balance the production of dihydrotestosterone (DHT), a hormone that can contribute to hair loss when present in excess. By maintaining optimal levels of DHT, zinc can help promote healthy hair growth.

While it’s possible to obtain zinc from our diets, some individuals may require additional zinc supplements to maintain normal levels. The question is, can these zinc supplements truly make a difference when it comes to promoting hair growth? Let’s find out.

Zinc Deficiency and Hair Loss

There is a basic link between zinc deficiency and hair loss. Research has shown that the person with lower zinc levels are more prone to various forms of hair shedding and thinning.

Zinc deficiency can be caused by poor dietary intake, malabsorption disorders, or increased zinc requirements due to certain medical conditions. When the body lacks sufficient zinc, it can disrupt the normal hair growth cycle, leading to increased hair fall and reduced hair density.

Symptoms of zinc deficiency include:

1. Thinning or shedding of hair
2. Dry, brittle hair
3. Slow wound healing
4. Frequent infections
5. Taste and smell disturbances
6. Decreased appetite

If left untreated, zinc deficiency can contribute to the development of alopecia, a condition characterized by patchy or widespread hair loss.

Link Between Zinc and Hair Growth

Many scientific studies have explained the relationship between zinc and hair growth. Let’s take a closer look at some of the research in this area:

A 2013 study published in the Dermatology and Therapy journal found that participants who were given zinc supplements had a significant improvement in hair density and a decrease in the hair shedding compared to the placebo group.

A 2017 review article in the Dermatology Practical & Conceptual journal summarized that zinc has role in hair growth and that zinc supplementation may be a useful treatment for certain types of hair loss.

A 2020 study published in the Journal of Cosmetic Dermatology shows that a combination of zinc, biotin and other nutrients was effective in improving hair growth and stopping hair loss with thinning hair.

These studies suggest that maintaining zinc levels may be an important factor in promoting healthy hair growth and preventing hair loss.

How Zinc Helps in Hair Growth?

Zinc support hair health and stimulate new hair growth by the following mechanisms:

Stimulation of Hair Follicle Growth

Zinc is needed in the proliferation and differentiation of hair follicle cells, which are responsible for the growth and development of new hair strands. Zinc stimulate cell division in hair follicles for the rapid division and growth of hair follicle cells and maintain hair growth.

Regulation of the Hair Growth Cycle

The hair growth cycle consists of three main phases: anagen (growth), catagen (transition) and telogen (resting). Zinc helps to regulate this cycle, ensuring smooth transition of hair follicles from one phase to the next and minimizing the risk of premature hair shedding.

Keratin Production

Zinc is required in the production of keratin, the primary structural protein that makes up the hair shaft, gives our hair it’s strength. Zinc helps to strengthen and fortify the hair strands, reduces breakage and shedding by supporting keratin synthesis.

Hormonal Balance

Zinc plays a role in regulating hormonal balance, particularly in the case of androgenetic alopecia (male-pattern baldness) and other hormone-related hair loss conditions. Zinc helps to neutralize the effects of dihydrotestosterone (DHT), a hormone that can contribute to hair follicle miniaturization and hair loss.

Antioxidant Properties

Zinc is a powerful antioxidant that help protect the hair follicles from oxidative stress and damage. This protection can promote healthy hair growth and prevent premature hair loss.

Sebum Production

Zinc plays a role in the regulation of sebum production, the natural oils that keep the scalp and hair moisturized. By maintaining a healthy balance of sebum, zinc can help to prevent dry, brittle hair and support the overall condition of the hair and scalp.

Immune System Support

Zinc is essential for a healthy immune system, which is important for maintaining the health and integrity of the hair follicles. By supporting the immune system, zinc can help prevent inflammation and autoimmune-related hair loss conditions.

Nutrient Absorption

Zinc has a role in the absorption and use of other essential nutrients, such as vitamin C, vitamin E and biotin, which are all important for hair growth and health.

Zinc Supplements Can Improve Skin Health

Zinc supplements also have a positive effect on our skin. Zinc is involved in the production of collagen, a protein that is essential for maintaining the structure and elasticity of our skin. By supplementing with zinc, we can support the skin’s natural healing and rejuvenation processes, helping to reduce the appearance of fine lines, wrinkles and other signs of ageing. Zinc also plays a role in the regulation of sebum production, which can help to prevent acne and keep our skin hydrated and balanced. Furthermore, zinc’s anti-inflammatory properties can be beneficial for soothing skin conditions like eczema, psoriasis and rosacea.

While choosing a zinc supplement, it’s important to opt for a high-quality product from a reputable company. Look for supplements that contain zinc in a bioavailable form such as zinc gluconate, zinc citrate or zinc picolinate. These forms of zinc are more easily absorbed by the body.

Note: *It’s important to note that while zinc supplements can be beneficial for hair growth, they are not a miracle cure. Hair growth is a complex process that involves genetics, overall health and lifestyle. Taking zinc supplements alone may not be enough to stimulate significant hair growth if other underlying issues are present.
