How To Grow High Porosity Hair

Buh-bye, breakage


High porosity hair is notoriously tough to grow. It's typically a pretty slow process, since high porosity hair often breaks off faster than it grows in. On the brightside, it's not impossible, as long as you're willing to put in the extra effort. Here are our top science-backed tips for growing out high porosity hair.

Check your diet

Crash diets aren't good for growth. It's pretty simple: if you don't eat a sufficient amount of nutritional food, your hair won't emerge from your scalp in good condition.

The good news? Most Americans consume a diet that's healthy enough to support normal hair growth. So if you're already eating a healthy-ish diet, theres no reason to go out and buy a bunch of fancy hair supplements. Save your money for something that'll actually work to help your hair grow.

Use a reparative conditioner

High porosity hair has lots of itty bitty holes in its armor, leaving it susceptible to breakage. And let's be real -- it doesn't matter how quickly your hair grows out of your scalp if way more of it is being prematurely snapped off. Fortunately, some ingredients, such as keratin, can provide a temporary band-aid on these little holes, protecting you from further breakage.

Chill out on the styling

High porosity hair doesn't like heat, water, combs, or brushes. If possible, limit styling to the absolute minimum. And yes, this even includes protective styles -- the less you mess with your hair, the less breakage you'll experience.

Opt for low-tension hairstyles

Tight braids are a no-no if growth is your goal. If doing your hair brings tears to your eyes, you'll want to switch to a more gentle method of styling. High porosity hair is extra-prone to snapping, so you'll want to reduce high-tension styling as much as possible.

Detangle with extra care

As tempting as brute force detangling might sound (so time efficient!) high porosity hair requires some serious TLC. Aggressively detangling runs the risk of yanking strands out en masse and setting you way back in your growth journey. Either trade in your comb entirely and switch to finger detangling or use a combination of gentle combing and finger detangling. The more finger detangling and the less combing, the better.

Wash a little less often

Even if you use the gentlest shampoo on the market, there's always a bit of damage that occurs when you expose your hair to the combination of water and scrubbing that washing entails. Consider waiting just one extra day before washing your hair -- you might find that it makes a big difference in the amount of breakage you experience.

Be careful when washing

You don't want to lose any more strands than necessary in the shower. High porosity hair is extra fragile when wet, since liquid seeps in and stretches the strand.

First lather up shampoo in your hands with a little extra water. Avoid scrubbing back and forth -- instead, wash in a single direction. Go towards your ends, not towards your roots. Going in the same direction as your cuticle minimizes the amount of mechanical stress that your tresses endure.

Shorten your showers

The longer that high porosity hair is exposed to water, the longer it remains in its extra-fragile wet state. Protect your hair by lessening the amount of time that it stays wet. Try to stay on task, and cut down on those dreamy minutes you spend staring at the wall while your hair is directly under the faucet.

Choose hair ties wisely

Friction isn't kind to high porosity hair. If your hair tie's elastic innards are exposed, it's probably time to toss it in the trash. And don't even think about tying hair back with a **shudders** rubber band -- that's a sure way of worsening your porosity by further weaking the hair cuticle. Fabric ties, especially scrunchies, are your friend.

Never heat style without a heat protectant

Rule of thumb: if it's too hot to touch it with your hands, don't let it touch your hair unless you've applied a heat protectant. Otherwise, risk your hair melting off mid strand.

Don't skimp on the conditioner

High porosity hair is notoriously dry. Dry hair is fragile. If you want your hair to keep increasing in length, you'll want to avoid the snappage by regularly applying conditioner.

Think about an ingredient switch

A lot of people believe that silicones = hair death. But the science simply doesn't back this claim up. In fact, silicones are actually super helpful for growth, since they protect the hair that you've already got.

Silicones form a protective armor around the hair cuticle (the outer layer of a hair strand) that helps keep the good stuff in high porosity hair, and the bad stuff out. They also act as heat protectants, and lubricate strands so that they're easier to brush through -- a big win for preventing growth loss via mechanical damage.

Drop that towel

Aggressively towel drying your tresses won't do you any favors. The rough fibers of the towel rub up against and strip away the hair cuticle, worsening porosity. Even worse -- aggressively towel drying has the potential to rip out or break off strands all together. Play it safe, and allow hair to air dry as much as possible.

Cover it up

Not only is the sun super bad for your skin, it's also no friend to your hair. Porosity is worsened through exposure to the sun's rays, increasing the fragility of the hair strand. Damage becomes noticeable after only 200 hours of exposure. Considering that some UV rays penetrate through glass windows, you'll be well served by covering your tresses with a hat, wig, or scarf.
