Men's Curly Hair Growth Hacks: Essential Oils, Co-Washes, and ACV

If you are growing out curly hair as a guy, the basics matter more than fancy products. Six hacks below, all cheap, all backed by either solid research or years of community use. None of these require a specialty store or a big budget. Pick two or three to add to your current routine and run them for a month before adding more.

The hacks split into two buckets: things you put in your hair and things you stop doing to your hair. Both matter. Most guys focus only on the first bucket and then wonder why their hair is not growing.

Hack 1: Peppermint Oil for Hair Growth

Peppermint oil has actual research behind it for hair growth. A 2014 study tested four substances on shaved mice: jojoba oil, peppermint oil, saline, and a control. By week three, peppermint oil produced the highest growth rate at 92 percent. That is significantly higher than every other substance tested.

How to use it without irritating your scalp:

• Add three to four drops to your shampoo bottle, conditioner bottle, or deep conditioner.
• Mix it into a hair mask along with a carrier oil like coconut or olive.
• Never apply pure peppermint oil straight to your scalp. It is too concentrated and will burn.

You can find peppermint oil at any health store, Whole Foods, Bristol Farms, or online. A small bottle lasts for months because you only use a few drops at a time. The cooling, tingling sensation when you wash is a bonus, but the real point is the growth signal it sends to your follicles.

Hack 2: Leave-In Conditioner Spray for Brittle Ends

If your ends feel dry and brittle between wash days, the answer is not pouring more leave-in into your hand and raking it through. That is more manipulation, which means more breakage. The answer is a leave-in conditioner spray.

The recipe is simple. Take your favorite leave-in, dilute it with water in a small spray bottle, and shake. Mist your hair when it feels dry, then seal with your favorite oil. Olive oil and coconut oil both work well. Oils do not add moisture. They lock in the moisture you already added with the spray.

This is the lightest-touch way to get water into your strands without undoing your wash day. For a full breakdown of how to handle frizz at the same time, see our halo frizz guide.

Hack 3: Overnight Hair Mask Before Shampoo

Shampoo strips your scalp's natural oils. That is its job. The problem is curly and coily hair needs those oils more than other hair types. The fix is an overnight oil mask the night before you wash.

Two cheap options:

• Coconut oil mask. Warm a few spoonfuls until liquid, work through dry hair from roots to ends, and put on a sleeping cap or do-rag. Sleep on it. Shampoo in the morning.
• Olive oil mask. Same protocol as coconut, slightly heavier. Better for high-porosity hair that needs serious sealing.

When you rinse out the next morning, use cool or lukewarm water, not hot. Hot water opens the cuticle and lets your hair lose moisture faster. Cool water seals the cuticle.

If you do not have time for an overnight mask, the next two hacks are faster alternatives.

Hack 4: Co-Washing With Conditioner

Co-washing means using only conditioner to clean your hair, no shampoo. The conditioner has mild surfactants that lift dirt and product without stripping oils.

When to co-wash:

• Mid-week refresh between full wash days.
• Days when your hair feels dirty but not actually dirty, like after a workout where you did not sweat much.
• When your scalp feels tight or itchy after a recent shampoo.

If you find that co-washing alone does not get your hair clean, dilute your shampoo with conditioner or water. The diluted version cleans without the harsh stripping. Some guys go full co-wash for two weeks and then do one regular shampoo to reset. Experiment and see what your scalp prefers based on your porosity.

Hack 5: Apple Cider Vinegar Rinse

Apple cider vinegar gets recommended a lot in curly hair communities, and it actually works. ACV clarifies your hair without stripping the natural oils, adds shine, and gives your curls bounce and volume.

The basic rinse:

1. Mix one tablespoon ACV with one cup water.
2. Add three drops of peppermint oil if you have it.
3. After shampooing and conditioning, pour the mix over your hair.
4. Let it sit for a minute, then rinse with cool water.

Once a month is plenty. Doing this every wash day will make your hair feel dry over time. The shine boost is real, especially for guys with darker hair. Curly and coily strands often look less shiny than straight hair because light cannot reflect off a flat surface, so the ACV cuticle smoothing actually helps with that.

For 3C and 3B guys, monthly ACV rinses can be the difference between hair that looks dull and hair that catches light.

Hack 6: Stop Touching Your Hair

This is the hardest one. Curly hair guys touch their hair constantly out of nervous habit. Every touch creates frizz and breaks the curl pattern.

Four rules:

• Sleep on a satin pillowcase or in a do-rag. Cotton creates friction overnight, which causes breakage and frizz. A satin pillowcase costs ten dollars and lasts for years.
• Use a t-shirt instead of a towel. Standard towels create massive friction. An old cotton t-shirt absorbs water without the rough texture.
• Use a pick only when necessary. Daily picking is one of the worst habits for length retention. Pick at the roots only for volume, and detangle once a week with slip during your wash day.
• Hands off when dry. Every time you mess with dry curls, you frizz the cast. If you need to fix something, mist with your leave-in spray first.

Putting It Together

You do not need to do all six at once. A practical month-one stack:

Run that for 30 days, then layer in anything else you want. The point of a routine is consistency, not complexity. If you want help figuring out which products in your current lineup are pulling weight and which ones are holding you back, Scrunchie scans your bottles and tells you what to keep, swap, or drop. Useful before you buy your seventh bottle of leave-in.
