What Each Ingredient Does
Grass-Fed Tallow
Tallow creates a hard, long-lasting shampoo bar with creamy conditioning lather. It helps add moisture and contributes to the overall durability of the bar.
Coconut Oil
Coconut oil boosts cleansing and creates fluffy bubbles. It helps remove excess oil and buildup from the hair and scalp.
Olive Oil
Olive oil adds gentle conditioning and helps create a milder shampoo bar that feels nourishing on the hair.
Castor Oil
Castor oil helps stabilize lather and adds extra bubbles while helping the shampoo bar feel smoother during use.
Lye
Lye is necessary for the saponification process that transforms oils into soap. Properly cured soap contains no remaining lye.
Essential Oils
Essential oils add natural fragrance and can help customize the shampoo bars depending on your preferences.
Popular options include:
- Lavender essential oil
- Rosemary essential oil
- Peppermint essential oil
- Tea tree essential oil
