Nourishing our body can impact the growth and strength of our hair. While nutrients and minerals impact the health of our hair, the benefits of iodine for hair growth are quite impressive. Iodine is an essential trace element naturally found in various food items and helps make thyroid hormones (1). By ensuring you’re consuming an adequate amount of iodine, you can keep the functioning of thyroid hormones under check. Iodine intake can be assessed by the conditions of the hair, and as such, iodine consumption has a potential impact on hair (2). So, if you want to renew the natural texture of your hair, iodine can come in handy. Let’s explore the benefits of iodine so that you can keep the consumption of this essential mineral in your body under check.

What Is Iodine?

Iodine

Iodine is a mineral the body needs to make thyroid hormones (1). Thyroid hormones facilitate many bodily functions at different stages of life. They contribute to bone growth and development in children (3). In adults, they help regulate metabolic functions and aid weight and energy management (4). By consuming adequate iodine per day, you can enhance the functioning of your body efficiently. Thyroid hormones are also crucial for the development of bones and brain during pregnancy and infancy (1). So, iodine has a significant role to play for different age groups.

Iodine deficiency has been associated with poor hair quality and inefficient development of hair follicles. With iodine deficiency, the production and functioning of thyroid hormones are also affected (1). Thyroid hormones play a crucial role in stimulating hair growth, and in the absence of thyroid hormones, hair growth may become stagnant (5). So, if your hair growth is impaired, you may need to check if you’re consuming iodine properly.

2. May Help Prevent Hair Aging

Premature aging of the hair may occur in the 20s or 30s and can lead to many hair disorders (6). The deficiency of thyroid hormone has been proven to cause early graying of the hair (7). By using iodine, you can overcome the deficiency of thyroid hormone (1). So, by making up for the deficiency of thyroid hormone, you can prevent the aging of your hair.

3. May Help Manage Dry And Brittle Hair

Dry, brittle, and dull hair has been associated with hypothyroidism or the lack of thyroid hormones (7). Iodine is mainly responsible for maintaining the levels of thyroid in our bodies (1). So, by consuming iodine, you can help treat dry and brittle hair to keep your hair strong and healthy.

4. May Help Hair Loss Prevention

Inadequate thyroid levels are one of the main factors for excessive shedding of the hair  (7). By consuming iodine, you can regulate thyroid hormone production and boost hair growth. 

5. May Help Prevent Androgenetic Alopecia

Androgenetic alopecia is one of the common hair loss disorders that can cause front hairline receding and thinning of the hair (8). Hypothyroidism can cause androgenetic alopecia both in children and adults (9). If you’ve noticed patterns of baldness, you might need to consider iodine consumption.
