It appears you can apply onions, or more specifically onion extract, to your scalp, particularly if you have an itchy scalp.
Applying onions or onion extract to the scalp may offer some benefits. According to research, onion's anti-inflammatory properties may help soothe an itchy scalp. (05-Aug-2020) Furthermore, you can combine onion extract with other natural ingredients to potentially calm your scalp.
However, consider the following before applying onions directly to your scalp:
- Concentration: Directly applying raw onion may be too strong for some individuals.
- Irritation: Some people may experience skin irritation or an allergic reaction. It is best to test a small area first.
- Smell: The strong odor of onions can be unpleasant.
- Preparation: It's more common to use onion juice or an extract rather than rubbing raw onion directly on the scalp.
Therefore, while the anti-inflammatory properties of onions may be beneficial, proceed with caution. Using onion extract diluted with other ingredients might be a more suitable approach.
