What 4B hair looks like
4B strands bend sharply instead of curling, so the hair forms a soft, cotton-like mass with little visible pattern until it is styled. It often mixes with 4A coils and 4C areas.
A 4B wash day
The American Academy of Dermatology suggests washing Black hair once a week or every other week, with conditioner every time.
- Pre-poo with oil or conditioner if your hair knots easily.
- Wash in sections, keeping each one twisted or clipped.
- Condition every wash; detangle with fingers first, then a wide-tooth comb, ends first.
- Put leave-in on wet hair, then a cream or butter to seal it.
- Style in sections: twists, braids, or gel smoothed through small sections for definition.
A 4B hair routine and what it costs
One product for each wash-day step, chosen only from products whose makers say they’re for 4B hair, priced at each maker’s own store. The left column takes the cheapest per ounce at every step; the right takes the one in the middle. We haven’t tested them, and how your own hair responds matters more than the price.

34 of the 41 products we list for 4B hair at these steps had a size in stock at the maker’s store when we read it, so only those are ranked. Some makers print “oz” without saying fluid or weight; we compare them as printed. Prices checked between and ; stores change them. Every price per ounce.
What usually goes wrong
With 4B, trouble mostly comes from tension and dryness. Combing a section that hasn’t been softened with conditioner snaps strands at the bends, and tight styles do the same over time. The AAD’s rule for braids and weaves is simple: if it hurts, it is too tight.
Products whose makers say they’re for 4B hair
These products’ own pages say they’re made for 4B hair, or for a range of curl patterns that includes it. The words are the maker’s; we haven’t tested these products, and how your own hair responds decides more than the label.
