The Best Haircare Routine for High Porosity Type 3 Curly Hair

Before starting your haircare routine, it’s important to know your hair porosity. Hair porosity refers to your hair's ability to absorb and retain moisture. There are three porosity levels: low, medium (normal), and high. Here’s a quick and simple way to test it:

The Float Test:

• Take a clean strand of your hair.

• Drop it into a glass of room-temperature water.

• Wait for about 2–4 minutes.

Result:

• If your hair floats on top, you have low porosity hair - your hair cuticles are tightly closed, and water struggles to penetrate.

• If it sinks slowly, your hair is medium/normal porosity.

• If it sinks quickly, your hair is high porosity - your cuticles are open and absorbs moisture quickly but loses it just as fast.

Once you’ve identified your hair porosity, you need a good healthy haircare routine for your specific hair type. If your hair floats to the top, you have low porosity hair, you can follow this➡️low porosity Haircare Routine for curly hair here.

If your hair sinks to the bottom, you have high porosity hair, the following routine will help you retain moisture, prevent oily buildup, and strengthen your hair. High porosity has open hair cuticles, making it easy for moisture to enter. High porosity curly hair can easily get dry, tangled and frizzy because it also loses moisture quickly, so we need to focus on detangling and deep moisturizing.

The goal of this haircare routine is to close the hair cuticles by using the right product to lock in the moisture without weighing down your curls. Whether you're dealing with heat damage, chemical treatments from hair dyes, or breakage, this is the best haircare routine for your high porosity curly hair. Let’s go through each step in detail.

Start with a gentle, hydrating shampoo that cleans your scalp without stripping away essential oils. Since high porosity hair loses moisture easily, avoid harsh shampoos that can make your hair even drier.

• What to Use: Choose a sulfate-free, moisturizing shampoo with ingredients like argan oil, glycerin, or aloe vera. These help soften and repair your hair cuticles. Avoid harsh sulfates like SLS (sodium lauryl sulfate) or SLES, which can dry out your hair.

• How to cleanse: Shampoo once a week. Use lukewarm (not hot) water and focus the shampoo on your scalp, gently massaging with your fingertips or a scalp scrubber for 1-2 minutes. Rinse with cool or lukewarm water.

High porosity curly hair needs thicker, moisturizing conditioners that moisturize and gently smooth out the hair cuticles to lock in the moisture. Use a moisturizing conditioner to moisturize and gently detangle and soften your hair.

• What to Use: Choose a rich, and creamy conditioner with ingredients like caprylic acid, aloe vera, and glycerin that draw in moisture.

• How to tone: Apply generously from mid-lengths to ends, and detangle your hair gently with your fingers or a detangling brush. Cover your hair with a shower cap and leave it on for 10-15 minutes. For extra penetration, use a warm towel or hooded dryer. Rinse with lukewarm or cool water to seal in the moisture.

A leave-in conditioner keep your hair moisturized throughout the day. This is one of the most important steps because it locks in moisture and define your curls and prevents fizziness.

• What to Use: Use a creamy leave-in conditioner that contains ingredients like aloe vera, panthenol (vitamin B5), or silk amino acids. Avoid thick butters that can cause buildup and weigh your hair down.

• How to moisturize: Apply to damp hair, focusing only on the mid-lengths and ends of your hair (do not apply directly on your scalp). Distribute evenly using your fingers or a wide-tooth comb.

Sealing is one of the most important steps for high porosity curls — it helps lock in moisture and reduce frizz by closing the cuticle. Use light, easy to absorb oils that lock in moisture.

• What to Use: Use a lightweight scalp oil or serum once a week. Look for ingredients like tea tree oil (for buildup), peppermint oil (for stimulation), or grapeseed oil (for lightweight moisture)

• How to use it: Apply a few drops of oil or serum to your palms and gently scrunch into your curls, focusing on your ends.

Always use a heat protectant before blow-drying, flat ironing, diffusing or curling your hair. Since high porosity curly hair is prone to dryness, always protect it before using heating tools.

• What to Use: If you're blow drying or diffusing your hair, always use a lightweight heat protectant spray that can withstand temperatures of up to 450°F. For daily styling, use a curl-enhancing mousse, foam, or light gel for extra hold and curl definition.

• How to use it: For best results, apply your styling product while your hair is still damp. Use the scrunching method to scrunch your curls upward for extra definition. Air dry or use a diffuser on low heat. If you style your hair frequently, do low maintenance protective styles like low buns, braids, or twists.
