Hair guide

4B hair, styled your way.

4B hair bends in sharp, Z-shaped angles rather than round curls, with a soft, cottony feel and serious volume. Here are ten hairstyles with how-tos, a simple routine for moisture, wash day and deep conditioning, and an honest look at texturisers.

The basics

The 4B hair type, explained

4B hair is a Type 4 texture. Instead of round coils, the strands bend in sharp, Z-shaped angles, so the pattern looks crimped and less defined than 4A. It is fluffy and full, it shrinks a lot, and strands can be fine or coarse.

The chart was popularised by stylist Andre Walker in the 1990s, and in his original version Type 4 ended at 4B: a visible curl pattern made you 4A, and no visible pattern made you 4B. The labels describe curl pattern only, not health or beauty. Every texture is beautiful, and most heads have a mix.

Next to its neighbours, 4A has springy S-shaped coils you can see clearly, and 4C has the tightest coils and the most shrinkage. For the full side-by-side, see our 4A, 4B and 4C hair chart.

Styling

Hairstyles for 4B hair

4B hair holds a shape brilliantly. Start with clean, moisturised hair, work in sections and let each style dry fully:

  1. 1
    Twist-out

    On damp, moisturised hair, twist two strands around each other to the ends with a little cream. Once dry, unravel with oiled fingertips and fluff the roots.

  2. 2
    Braid-out

    Plait instead of twisting for a more stretched, crimped finish. Chunky plaits give big waves, smaller ones a tighter texture.

  3. 3
    Bantu knots

    Twist a section, wind it into a small knot and tuck the end under. Wear the knots, or take them down when dry for a springy knot-out.

  4. 4
    Wash and go

    On soaking-wet hair, smooth leave-in and then gel through each section, and leave it alone while it dries. Shrinkage is part of the look.

  5. 5
    Puff

    Gather your hair into a soft scrunchie, never a tight elastic. Fluff it out and keep your hairline relaxed, not dragged back.

  6. 6
    Two-strand twists

    Twist small sections from root to tip and seal the ends with oil. Low manipulation, easy to moisturise, and tomorrow's twist-out.

  7. 7
    Flat twists

    Like cornrows, but with two strands twisted flat to the scalp. Unravel them later for a wavy flat-twist-out.

  8. 8
    Cornrows

    Ask for neat, loose rows, and change direction each time so the same areas are not always under strain. A flat base for a wig, too.

  9. 9
    Box braids or knotless braids

    Choose an experienced braider and light extensions, because long, heavy braids and beads pull on your roots. The British Association of Dermatologists advises taking braids out within 6 weeks.

  10. 10
    Blow-out or silk press

    For an occasional stretched look, use a heat protectant and the lowest heat that works. If you press, the American Academy of Dermatology suggests a ceramic comb or iron no more than once a week.

Want a fuller puff or twist-out? Afro kinky clip-ins blend with natural 4B texture and come out at night.

Keep every style comfortable. Tight ponytails, buns and braids can cause traction alopecia, so leave your edges out where you can and never put up with a sore scalp.

Daily care

How to moisturise 4B hair

4B hair dries out easily. The British Association of Dermatologists explains that your scalp's natural oil cannot travel easily along tightly curled hair, and dry hair breaks more easily. Layer moisture on damp hair:

  1. Liquid: water or a water-based leave-in, the part that actually hydrates.
  2. Oil and cream: in the LOC order (liquid, oil, cream) or LCO (liquid, cream, oil). Keep whichever leaves your hair softer for longer.
  3. Extra on the ends, the oldest, most fragile part of each strand.

Refresh every few days with a mist of water or leave-in, then reseal. Coated but still dry? Use less oil and more water-based product: oil slows moisture loss, but it does not hydrate.

At night, wrap your hair in a satin or silk bonnet or scarf, or sleep on a satin or silk pillowcase, to cut friction.

Wash day

Wash day for 4B hair

The British Association of Dermatologists suggests washing every 1 to 3 weeks, or whenever you have build-up or an oily scalp. For 4B hair:

  1. 1
    Section first

    Split your hair into chunky twists or plaits. Very dry? Coat the lengths in oil or conditioner first.

  2. 2
    Cleanse the scalp

    Massage a gentle shampoo into your scalp with your fingertips and rinse without undoing the sections.

  3. 3
    Condition and detangle

    Use plenty of rinse-out conditioner, then detangle each section with your fingers and a wide-tooth comb, ends first.

  4. 4
    Deep condition

    On most wash days, follow with a deep conditioner (see below).

  5. 5
    Leave-in and seal

    Apply your leave-in to damp hair and seal with oil or cream, section by section.

  6. 6
    Dry stretched

    Blot with a microfibre towel or cotton T-shirt, then dry in chunky twists or plaits to stretch the hair and cut down on knots.

Skip fine-tooth combs: a wide-tooth comb, or a soft brush with widely spaced, coated bristles, is far kinder.

Treatments

Deep conditioning 4B hair

A deep conditioner is a richer treatment you leave on longer than your everyday one. It softens 4B coils and adds slip. Aim for every wash day, or every other one if your hair stays soft. Choose by feel:

  • Moisturising masks, with humectants, oils and butters, for dry, rough or crunchy hair.
  • Protein treatments, with hydrolysed proteins, now and then for hair that feels mushy or overstretched, or after colour or heat.
  • Balance the two. Stiff or straw-like after protein? Go back to moisture for a while.
  1. 1
    Apply to damp hair

    Squeeze out excess water and work the conditioner through each section, ends first.

  2. 2
    Cover and wait

    Put on a plastic cap, with a warm towel on top if you like, and leave it for the time on the label.

  3. 3
    Rinse and seal

    Rinse with lukewarm water, then apply your leave-in and seal.

Hot oil treatments help too: the American Academy of Dermatology suggests one twice a month for extra moisture and elasticity.

Chemical treatments

Texturiser on 4B hair: the honest trade-offs

A texturiser (spelt texturizer in the US) is a mild chemical relaxer, usually left on for less time, to loosen your curl pattern rather than straighten it. Like any relaxer, it breaks and rearranges bonds inside the hair, and the change is permanent.

People choose it for easier detangling, quicker styling and less shrinkage. Weigh up the trade-offs first:

  • It is permanent. New growth comes in natural, so keeping the look means touch-ups: on new growth only, never over treated hair, and at least 6 weeks apart, says the British Association of Dermatologists.
  • Results are hard to predict, especially if your 4B hair has more than one texture.
  • Treated hair is weaker. Relaxed hair has been found to have less cystine, a building block of hair's strongest bonds, consistent with fragile hair.
  • It can burn. Scalp burns can cause permanent hair loss, and relaxers can trigger an itchy rash.
  • Timing matters. UK dermatologists advise 2 weeks between relaxing and colouring or heat straightening, and relaxers are not compatible with bleached hair.
  • Health questions. Relaxers have been linked with a higher risk of central centrifugal cicatricial alopecia (CCCA), a scarring hair loss seen in Black women. In a US National Institutes of Health study, women who used straighteners or relaxers more than four times a year were more than twice as likely to develop uterine cancer: an estimated 4% by age 70, against 1.6% of women who never used them. That is a link, not proof of cause.

Still keen? See a stylist experienced with relaxers on Afro hair and ask for a strand test on a hidden section first. They should protect your hairline, ears and partings with a barrier such as petroleum jelly, and never leave it on longer than directed.

Curious about a looser texture? Try a kinky curly wig first: no chemicals, no commitment.

Sensitive scalp, a scalp condition or any hair loss? Talk to your GP or a dermatologist before any chemical treatment.

Wigs

Wigs that blend with 4B hair

Wigs are not the answer to everything, but they can give 4B hair a break from daily styling and heat. Worn over loose cornrows or twists that you keep clean and moisturised, a wig can be a protective style, says the British Association of Dermatologists.

Leaving some hair out? Match the wig to how you wear your leave-out, not how it grows:

  • Afro kinky matches natural, unstretched 4B hair, with no heat needed to blend.
  • Kinky straight looks like 4B hair after a blow-out. Blend it with a low-heat blow-out or a heatless stretch such as a braid-out.

That choice matters, because heat-styling leave-out to match a wig can cause long-term damage if you overdo it. A V-part wig leaves a small V of your own hair at the top, so match it with care. Prefer to leave nothing out? A headband wig sits behind your hairline with no lace or glue, giving your edges a rest. Keep the band comfortable, not tight.

Moisturise your leave-out, skip daily heat and wrap it at night. Take your wig off before bed, and give your own hair regular breaks.

Questions

4B hair, answered.

Anything else? Email bolt70business@gmail.com and a real person will help.

What does 4B hair look like?

Tightly coiled hair that bends in sharp, Z-shaped angles instead of round curls. It looks fluffy and full, feels cottony and shrinks a lot as it dries.

What are the best protective styles for 4B hair?

Twists, flat twists, cornrows, braids and wigs over loose cornrows all tuck your ends away. Keep them comfortable, never tight, and take breaks between styles.

How often should I deep condition 4B hair?

Every wash day, or every other one if your hair stays soft. Use a moisturising mask most of the time and a protein treatment now and then.

Is a texturiser bad for 4B hair?

Not automatically, but it is permanent, unpredictable on 4B hair and leaves treated hair more fragile. If you go ahead, see an experienced professional and ask for a strand test first.

Which wig texture blends with 4B hair?

Afro kinky blends with natural 4B hair, and kinky straight with 4B hair that has been blown out or pressed. Match the wig to how you wear your leave-out.
