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

🧴 Ingredients (makes ~6 bars)

• 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

1. Prepare safety gear: Wear gloves, goggles, and long sleeves. Work in a well-ventilated area.
2. 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.
3. Melt the oils: Combine all oils and butters in a heat-safe pot and melt over low heat. Cool to ~100–110°F.
4. 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).
5. Add rosemary: Stir in essential oil and any herbs or rosemary-infused oil.
6. 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)

Ingredients

• 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

1. Melt the base in a double boiler or microwave (short bursts).
2. Add oils and rosemary, stirring gently.
3. Pour into molds and let cool for several hours.
4. Unmold and use immediately — no curing needed.

💚 Tips

• 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)

🧴 Ingredients (makes about 4 bars)

• 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

1. 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.
2. Add oils: Once melted, stir in castor oil and olive (or jojoba) oil thoroughly.
3. Add rosemary: Stir in rosemary essential oil (and peppermint, if using). If you want a natural look, sprinkle in a little dried rosemary.
4. Pour into molds: Quickly pour the mixture into your soap molds before it starts to harden.
5. Set & unmold: Let the bars cool for several hours (or refrigerate 1–2 hrs). Once firm, pop them out of the molds.
6. 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

• 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

• 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.
