Progressive hair loss has a cosmetic and social impact. Hair undergoes three stages of hair cycle: the anagen, catagen, and telogen phases. Through cyclical loss and new-hair growth, the number of hairs remains relatively constant. A variety of factors, such as hormones, nutritional status, and exposure to radiations, environmental toxicants, and medications may affect hair growth. Seaweed is known for its rich source of vitamin and minerals including iodine which is said to help increase hair regrowth.

Seaweeds are natures wonders and are a rich source of Omega-3 fatty acids.

When the body receives the benefits of omega- 3, a person’s hair follicles get the right amount of nutrients so as to stimulate growth.

Moreover, omega-3s in seaweed also improve blood circulation in the scalp, which is essential for hair growth.

Seaweed also contains well-known elements such as collagen and other nutrients that are responsible for hair recovery, hydration, mineralisation and also its thickness.

Owing to the abundance of zinc and vitamins A and C in some seaweed, they may also stimulate hair growth and production.

In addition to containing the antioxidant vitamins A, C and E, seaweed boasts a wide variety of beneficial plant compounds, including flavonoids and carotenoids.

These have been shown to protect your body’s cells from free radical damage thus helping to boost hair regrowth.

In a study with the US National Library of Medicine National Institutes of Health, hair-loss preventing the effect of Grateloupia elliptica was analysed.

The study noted: “This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss.

“When immortalized rat cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased.

“In addition, the G. elliptica extract significantly inhibited the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia.” 

Iodine is a trace mineral that helps make thyroid hormones, which help keep cells and the metabolic rate (the speed at which chemical reactions take place in the body) healthy, explains the NHS.

Research indicates that when your thyroid hormone levels are low, your hair follicles may stop regenerating.

Over time, this may result in hair loss. This is where seaweed comes into play as it’s a rich source of iodine helping to halt a person’s hair loss.

Other health benefits of seaweed include:

  • Improves thyroid function
  • Good source of vitamins and minerals
  • Supports gut health
  • Helps with weight loss
  • Reduces heart disease risk
  • Reduce type 2 diabetes risk
