Hey, curlfriend, If you’ve been struggling to keep your 4C low porosity hair moisturized, you’re not alone. Low porosity hair has a tightly packed cuticle structure that makes it resistant to moisture absorption, but once you learn the right techniques, your hair will thrive. This guide will walk you through the best ways to keep your low porosity 4C hair hydrated, soft, and healthy. Plus, I’ll recommend some amazing products available to make your hair care routine easier.

Understanding Low Porosity 4C Hair

Low porosity hair has cuticles that lay flat and tight, making it hard for water and products to penetrate. This means moisture tends to sit on top of the hair rather than being absorbed. If your hair takes a long time to dry, repels water when wet, or struggles to absorb products, you likely have low porosity hair.

Key Challenges of Low Porosity 4C Hair:

• Product Buildup: Since moisture doesn’t easily penetrate, heavy products can sit on the hair, causing buildup.
• Difficulty Absorbing Moisture: Water and hydrating products take longer to be absorbed.
• Protein Sensitivity: Excessive protein treatments can cause stiffness and breakage.

The Best Moisturizing Routine for Low Porosity 4C Hair

1. Use Warm Water or Steam to Open Cuticles

Since the cuticles on low porosity hair are tightly sealed, using heat helps to open them, allowing moisture to penetrate.

• Rinse your hair with warm water before applying products.

• Sit under a hooded dryer for 10-15 minutes after applying deep conditioner.
