Yes, applying onion juice to the scalp may promote new hair growth.
Here's a breakdown of why this is believed to be the case:
- High Sulfur Content: Onions are rich in dietary sulfur, which is a crucial element for amino acids. These amino acids are the building blocks of proteins like keratin.
- Keratin Production: Keratin is essential for hair structure and strength. Because sulfur is required for keratin production, onion juice may support healthier hair.
- Strengthens Hair & Prevents Breakage: The increased keratin production could strengthen hair and help to prevent breakage, such as split ends.
| Onion Component | Benefit |
|---|---|
| Sulfur | Key component of keratin, a hair protein |
| Amino Acids | Building blocks of proteins, including keratin |
Therefore, using onion juice on your scalp could potentially contribute to hair growth by strengthening hair and preventing breakage due to its high sulfur content which is needed for the production of keratin.
