Both onion and garlic offer potential benefits for hair growth and health, primarily due to their high sulfur content, which is crucial for hair protein structure. However, subtle differences exist.
Onion's Advantages:
- A 2014 study in the Journal of Dermatology showed increased hair growth in participants using onion juice.[Healthshots]
- High sulfur content contributes to stronger hair follicles and reduced shedding.[Quora, SwirlyCurlyHair]
Garlic's Advantages:
- Possesses stronger antimicrobial properties than onion, improving scalp health.[Times of India, Editorji]
- Contains selenium and zinc, essential for hair health.[Times of India]
- May promote thicker, longer, and more lustrous hair.[Editorji]
Conclusion:
While both are beneficial, garlic's superior antimicrobial properties and additional nutrients like selenium and zinc give it a slight edge for overall hair health. Onion remains a viable option, particularly supported by research showing its effectiveness in promoting hair growth. The best choice may depend on individual needs and scalp conditions.
