Sea Kelp Reversed Her Hair Loss After Losing Weight: ‘I Finally Have the Thick Hair I Wanted!’

Marissa Davenport, 50, felt hopeless when she started to notice her hair breaking and falling out after working so hard to lose 40 pounds. Over-the-counter shampoos and conditioners that promised to stimulate hair growth didn’t work, and Marissa felt like she was running out of options. But once she started searching online for a solution, she was surprised to learn that sea kelp can help reverse hair loss. And it turns out the natural remedy was exactly what she needed to restore healthy new growth.

Her hair loss was an unexpected side effect of losing weight

Oh no, not again, Marissa sighed, pulling another clump of hair from her shower drain. After embarking on a weight-loss journey in 2020 and losing more than 40 pounds, Marissa’s hair became dry and brittle and began falling out. No one tells you this can be a side effect of losing weight!

Marissa tried a variety of treatments, but each growth serum and shampoo only drained her wallet. Frustrated, she began searching online for a natural, affordable remedy— and one surprising ingredient kept surfacing again and again in her research: sea kelp!

A natural remedy to prevent hair loss

Fascinated, Marissa found studies revealing how sea kelp, an iodine-rich large, brown algae, has a powerful mix of vitamins and minerals that nourish follicles and boost scalp circulation to reduce shedding and promote growth. Supporting thyroid hormone production is another key to maintaining a healthy hair growth cycle—and the iodine in the sea kelp can be absorbed through the scalp, she mused. 

Marissa was also surprised to learn that thyroid-regulating iodine levels wane during menopause, which can also impair hair growth. I should give it a try! she thought, hopeful. 

On Instagram, Marissa came across Erin Davis, a certified natural haircare formulator and creator of Mermaid Texturizing Growth Spray ($26 for 2 oz., ErinandMaeCo.com). The spray combines the study-backed sea kelp Marissa had researched, along with antioxidant-rich rosemary to reduce breakage and add shine and sea salt to gently exfoliate the scalp and absorb excess oil.
