Much like bananas and apples, watermelons boast a high Vitamin C content. Vitamin C helps to carry nutrients such as collagen to the scalp, which is vital if you want your hair to be strong and damage-resistant.
Moreover, watermelon contains Arginine, which is an essential amino acid and has been linked to circulation stimulation in the scalp. Proper circulation is one of the most important contributors to hair growth, so this is a huge bonus.
And it’s not only the flesh of the watermelon that can help your hair to grow healthy and strong. The oil from the seeds is also an excellent moisturizer that can help to remedy dry and brittle hair.
In order to make a moisturizing, strengthening, and stimulating hair mask out of watermelon, many hair care experts recommend mixing mashed watermelon with mayonnaise and massaging the resultant paste all over the scalp so that it can absorb into the roots.
