• Treats Dandruff: Moisturizes the scalp, relieves flakiness, and helps manage dandruff.

6. Tames Frizz and Defines Curls

• Restores Moisture: Tames coarse, unruly strands, and makes curls more defined and manageable.

How to Use Peanut Oil for Hair

• As a pre-wash deep conditioning treatment: Massage warm peanut oil into scalp and hair, wait for 30 minutes, rinse thoroughly.
• As a leave-in serum: Apply a few drops to damp or dry ends to fight frizz.

Tip: Use peanut oil up to 1–2 times per week for optimal results. Avoid if you have oily scalp or are prone to acne on the hairline.

Other Uses of Peanut Oil
