Hair is made out of protein and it needs protein to grow.
Sugar slows down the absorption of protein.
High sugar intake can cause a spike in blood insulin levels and androgens (male hormone), which causes inflammation of the scalp and leads to the shrinking of hair follicles, and cause the hair to fall out.
Some common sugar-loaded foods are soft drinks, chocolates, and sweets.
Sugar-free foods substitute sugar with artificial sweeteners.
Specifically, one named ASPARTAME, which can cause hair loss and thinning hair when consumed in excessive amounts.
To avoid this, there are alternatives which can be replaced.
HONEY or JAGGERY are natural ones to be replaced absolutely and recommended as HEALTHY!!!
