Here’s a simple, natural recipe for a rosemary castor oil shampoo bar that promotes hair growth, adds shine, and gently cleanses. You can make it either the cold process (classic soap-making) or melt-and-pour way — I’ll show both below.
🌿 Cold Process Rosemary Castor Oil Shampoo Bar[edit | edit source]
🧴 Ingredients (makes ~6 bars)[edit | edit source]
- 10 oz Olive oil (moisturizing)
- 5 oz Coconut oil (cleansing & lather)
- 4 oz Castor oil (shine, promotes growth)
- 3 oz Shea butter or cocoa butter (conditioning)
- 1.8 oz Lye (sodium hydroxide) — use a lye calculator if you adjust amounts
- 4.5 oz Distilled water
- 10–15 drops Rosemary essential oil
- (optional) 1 tsp powdered rosemary or infused rosemary oil
🔥 Instructions[edit | edit source]
- Prepare safety gear: Wear gloves, goggles, and long sleeves. Work in a well-ventilated area.
- Make the lye solution: Slowly add the lye to the distilled water (never the reverse!). Stir until dissolved. Let it cool to about 100–110°F.
- Melt the oils: Combine all oils and butters in a heat-safe pot and melt over low heat. Cool to ~100–110°F.
- Combine lye and oils: Slowly pour the lye solution into the oils. Blend with an immersion blender until you reach trace (a light pudding consistency).
- Add rosemary: Stir in essential oil and any herbs or rosemary-infused oil.
- Pour and cure: Pour into silicone molds, cover, and insulate for 24–48 hours. Once firm, unmold and cure for 4–6 weeks in a dry, ventilated area.
⚗️ Easier Melt-and-Pour Version (no lye handling)[edit | edit source]
Ingredients[edit | edit source]
- 1 lb melt-and-pour soap base (goat’s milk, shea butter, or castile)
- 1 tbsp Castor oil
- 1 tbsp Olive oil
- 10–15 drops Rosemary essential oil
- (optional) 1 tsp dried or ground rosemary
Steps[edit | edit source]
- Melt the base in a double boiler or microwave (short bursts).
- Add oils and rosemary, stirring gently.
- Pour into molds and let cool for several hours.
- Unmold and use immediately — no curing needed.
💚 Tips[edit | edit source]
- To boost hair growth, you can add a few drops of peppermint essential oil along with rosemary.
- To make rosemary-infused oil, steep fresh rosemary in olive or castor oil over low heat for ~30 minutes, then strain.
- Store bars in a dry, well-drained soap dish to extend life.
Would you like me to tailor this recipe for a specific hair type (e.g., dry, oily, curly, color-treated)? I can adjust the oils and ratios for that.

Perfect 👍 — if you want to make a rosemary castor oil shampoo bar without lye, the best and safest way is to use a melt-and-pour soap base. The base has already gone through the lye process (saponification), so it’s completely safe to handle and customize.
Here’s how to do it:
🌿 Rosemary Castor Oil Shampoo Bar (No Lye Recipe)[edit | edit source]
🧴 Ingredients (makes about 4 bars)[edit | edit source]
- 1 lb (16 oz) melt-and-pour soap base – choose one for your hair type: • Goat’s milk – gentle, creamy, for dry scalp • Shea butter – rich and moisturizing • Castile (olive oil) – light and mild for oily scalp
- 1 tbsp Castor oil (shine & hair growth)
- 1 tbsp Olive oil or Jojoba oil (conditioning)
- 10–15 drops Rosemary essential oil (stimulates scalp)
- (Optional) 5 drops Peppermint essential oil (refreshing & boosts circulation)
- (Optional) 1 tsp dried or ground rosemary, or 1 tsp rosemary-infused oil
- Soap mold (silicone works best)
🔥 Directions[edit | edit source]
- Chop & melt the base: Cut your soap base into small cubes and melt it in a double boiler or microwave (10-15 sec bursts, stirring between). Don’t overheat — it should be fully melted but not boiling.
- Add oils: Once melted, stir in castor oil and olive (or jojoba) oil thoroughly.
- Add rosemary: Stir in rosemary essential oil (and peppermint, if using). If you want a natural look, sprinkle in a little dried rosemary.
- Pour into molds: Quickly pour the mixture into your soap molds before it starts to harden.
- Set & unmold: Let the bars cool for several hours (or refrigerate 1–2 hrs). Once firm, pop them out of the molds.
- Cure (optional but helps): Let the bars sit out for 24–48 hrs to harden more — this helps them last longer in the shower.
💚 Use[edit | edit source]
- Rub the bar directly onto wet hair or between your hands to create a lather.
- Massage into scalp, rinse thoroughly, and follow with a light conditioner or an apple-cider-vinegar rinse if you like.
🪶 Tips[edit | edit source]
- For dry or curly hair, add 1 tsp of shea butter when melting the base.
- For oily hair, add 1 tsp bentonite clay or activated charcoal.
- Store bars in a draining soap dish to prevent mushiness.
Would you like me to give you a version that’s 100% plant-based/vegan (no goat’s milk base)?
