How to use castor oil for hair growth
For scalp application: Warm 1–2 teaspoons of castor oil between your palms. Part your hair and apply directly to the scalp in sections. Massage in circular motions for 5 minutes. Leave on for at least 2 hours (or overnight with a shower cap). Shampoo out thoroughly — you may need two washes.
For hair length and ends: Apply a small amount to the ends of dry hair before styling. This seals the cuticle and reduces split ends.
The science behind castor oil and rosemary for hair
Castor oil's ricinoleic acid has anti-inflammatory properties that may help with the scalp conditions underlying hair loss. A 2023 review noted its potential for improving hair texture and reducing breakage, though clinical evidence for regrowing hair remains limited.
Rosemary oil has stronger clinical support. A 2015 study in Skinmed journal found rosemary oil comparable to 2% minoxidil for increasing hair count after 6 months. The 2023 TikTok trend was based on real science.
Our recommendation: use both together
For best results, combine Handcraft Blends Castor Oil as the base with Rosemary Essential Oil added in. The castor oil conditions and may strengthen existing hairs, while the rosemary may stimulate new growth at follicle level.
