Type 3B Hair
Medium Density · High Porosity
Type 3B curls are springy, defined ringlets full of personality and volume. Medium density gives your hair a visibly healthy and full appearance. High porosity means your cuticle has gaps or is raised, so moisture is absorbed quickly but escapes just as fast. The result is hair that often feels drier than expected, is prone to frizz, and can be vulnerable to breakage without the right care. The good news is that medium density gives you enough strands to work with and the right routine transforms how this combination looks and behaves.

How to Grow Your Hair
Layer your products to seal moisture in
High porosity 3B hair needs moisture to be sealed in immediately or it evaporates before it can benefit the hair. Use the LOC or LCO method after every wash. Apply a liquid leave-in first, then a curl cream or light oil, then seal with a heavier butter or oil like shea butter, castor oil, or avocado oil. Work through your hair section by section to ensure every spiral is treated from root to tip.
Protein every two to three weeks
High porosity hair has structural gaps in the cuticle that protein fills temporarily, making the strand stronger and better able to retain moisture. For 3B curls, this also means your spirals bounce back more reliably after drying. Use a hydrolysed protein treatment every two to three weeks, alternating with your deep conditioning sessions, and watch the overall resilience of your curls improve over time.
Cool water rinses after conditioning
Hot water opens the cuticle even further on high porosity hair and makes moisture retention harder. Always finish your wash with a cool or cold water rinse to help close the cuticle, reduce frizz, and smooth the surface of your 3B spirals. The difference in definition and shine after a cool rinse is very noticeable.
Scalp massages for steady growth
Medium density gives you a healthy number of follicles to work with. Keep them all active and producing strong strands with regular scalp massages using castor oil or a rosemary growth blend. Five minutes three to four times a week, worked through the scalp in sections, is enough to see a measurable difference in growth rate over a few months of consistency.
Gentle detangling only on wash day
High porosity 3B hair is prone to tangling and snapping when handled dry. Only detangle on wash day when your hair is fully saturated with a slippery conditioner. Start at the ends and work your way up slowly using your fingers or a wide-tooth comb. Never rush this step and avoid any detangling between wash days unless absolutely necessary.
Satin bonnet every night
High porosity hair loses moisture overnight more than any other type. A satin bonnet is better than a pillowcase for this combination because it fully encloses your hair. Pineapple your 3B curls gently at the top with your Froband before covering and your spiral definition will be largely preserved through the night without any damaging friction.
