Buying Guide: Key Considerations For Curly Hair
- Hydration versus cleanse: Curly hair often benefits from bars that prioritise moisture (oils, butters, humectants) while still providing a effective cleanse. Look for bars that include argan oil, shea butter, or coconut oil.
- Silicone-free and sulphate-free formulas: These reduce buildup on curls and minimise cuticle damage, helping maintain curl texture and bounce over time.
- Protein balance: Some bars use proteins (rice protein, keratin alternatives) to improve strength and reduce breakage. Balance is key; too much protein can make curls feel stiff.
- Gentle cleansers: Natural foaming agents or milder cleansers help preserve moisture and protect colour-treated curls, preventing frizz and dullness.
- Scalp health: A healthy scalp supports hair growth and curl definition. Choose bars with scalp-friendly ingredients and avoid harsh detergents.
- Eco-friendly packaging: Plastic-free, recycled or recyclable packaging aligns with sustainable routines often preferred for curly hair care.
- Fragrance and sensitivities: If you have a sensitive scalp, review fragrance blends (geranium, ylang-ylang, citrus) and opt for fragrance-free or hypoallergenic options if needed.
- Usage and travel: Solid bars are travel-friendly and reduce plastic waste. Ensure the bar is easy to dry between uses to prevent mushy residue.
- Color-treated and treated hair: For dyed curls, look for gentle formulas with color-safe credentials to minimise fading and maintain vibrancy.
- Maintenance routine: Consider alternating bars with occasional conditioner bars or liquids to prevent over-drying; this supports a balanced curl care routine.
