Type 3B Hair
High Density · Low Porosity
Type 3B curls are springy, tightly defined ringlets that form naturally voluminous styles. High density amplifies that volume significantly, giving you thick, full hair with a lot of presence. Low porosity means each strand has a tightly sealed cuticle that makes moisture absorption a challenge. Products sit on top of the hair, build-up accumulates quickly across the dense hair, and the hair can feel dry despite looking full. This is a powerful combination when cared for correctly and the volume you have is genuinely enviable.

How to Grow Your Hair
Steam is non-negotiable
Getting moisture into high density low porosity 3B hair requires sustained heat. A steamer or hooded dryer session with your deep conditioner every single wash day is the single most impactful change you can make. Apply your conditioner in sections to warm, freshly washed hair and sit under heat for 20 minutes. This ensures moisture penetrates through the full depth of your dense hair and into every sealed strand.
Apply all products section by section
High density hair makes it very easy for products to coat only the surface strands while the inner layers miss out. Divide your hair into four to six sections and apply your leave-in, gel, and any styling products to each section separately. This is the only reliable way to ensure even moisture distribution and consistent curl definition throughout the full thickness of your hair.
Clarify every two weeks
High density low porosity hair is the combination most prone to build-up. With so many strands gripping product residue and a cuticle that resists letting it go, the scalp can become congested faster than you realise. Clarify every two weeks without exception. A congested scalp directly slows growth, so this is not an optional step. Follow immediately with deep conditioning to restore moisture.
Sectioned scalp massages
With high density hair, a surface-level scalp massage does not reach the follicles underneath. Part your hair in sections and massage each area of the scalp directly using jojoba or grapeseed oil. Work through the whole scalp systematically so every follicle gets attention. Five minutes total, three to four times a week, done consistently over months, delivers real results.
Lightweight products only
It can feel counterintuitive to use light products on thick, dense hair but it is exactly what low porosity needs. Heavy formulas sit on the surface, do not absorb, and compound the build-up problem. Water-based leave-ins, aloe vera gels, and light curl milks absorb best and wash out cleanly. Save any richer products for the ends only.
Large satin bonnet every night
High density 3B hair generates a lot of volume and friction overnight. A large satin bonnet is the best solution as it accommodates the full size of your hair and eliminates friction across every strand. Pineapple your curls at the crown with your Froband before covering and you will preserve your spiral definition and volume through the night.
