After giving birth last year, I experienced significant hair shedding, which gave me a deeper understanding of just how emotional hair loss can be. While natural oils for hair growth aren’t miracle cures, many are effective at restoring thickness and confidence. For those looking to avoid pharmaceutical treatments, they can be a worthwhile option to consider.
When applied directly to the scalp, certain oils can reduce irritation, fight bacteria, supply fatty nutrients to the roots, and even improve blood circulation. According to William Gaunitz, WTS, a certified trichologist and founder of Advanced Trichology Products, these benefits may help ease conditions such as psoriasis, dandruff, seborrheic dermatitis, scarring alopecia, and general hair thinning.
Our top recommendation is The Ordinary’s Multi-Peptide Serum. This lightweight serum blends castor oil, which helps improve thickness and scalp health, with multiple peptides that can show visible results in as little as two weeks. But there are many other highly effective oil-based treatments worth exploring depending on your hair type and needs.
