The Best Haircare Routine for Low Porosity Type 2 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. If you have High Porosity Type 2 wavy hair, you can follow this➡️ high porosity Haircare Routine here to learn how to properly moisturize, and protect your wavy hair.

Once you’ve identified your hair porosity, you need a good healthy haircare routine for your specific hair type. If the float test shows you have low porosity hair, the following routine will help you retain moisture, prevent oily buildup, and strengthen your hair.

Low porosity has closed hair cuticles, making it difficult for moisture to enter. Low porosity wavy hair can feel dry, frizzy, and tangled, so we need to focus on sealing in the moisture.

The goal of this haircare routine is to open the hair cuticles by using the right product that lock in moisture, and keep your hair hydrated, soft, and healthy. Whether you're dealing with heat damage, chemical treatments from hair dyes, or environmental factors, this guide will help you create the best haircare routine for your low porosity wavy hair. Let’s go through each step in detail.

Start with a clarifying shampoo that cleans your scalp without stripping away essential oils. Low porosity hair easily builds up residue because products tend to sit on the surface rather than absorb. Cleansing is important to keep your scalp clean and your waves defined.

• What to Use: Choose a sulfate-free, clarifying shampoo with ingredients like apple cider vinegar, or salicylic acid. Avoid harsh sulfates like SLS (sodium lauryl sulfate) and SLES, that 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 to close the hair cuticles.

After shampooing, your hair needs hydration. Low porosity wavy hair needs light, water-based conditioner that adds moisture without weighing down your hair. Use a moisturizing conditioner to moisturize and gently smooth out your hair cuticles to lock in the moisture.

• What to Use: Choose a lightweight conditioner with ingredients like caprylic acid, aloe vera, and glycerin to provide draw in moisture and hydration.

• How to tone: Apply generously from mid-lengths to ends, and detangle your hair gently with your fingers or a wide-tooth comb. 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 the moisture in.

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

• What to Use: Use a lightweight, water-based leave-in conditioner or mist that contains ingredients like aloe vera, panthenol (vitamin B5), or silk amino acids. Avoid thick creamy leave-ins or oils 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.

Low porosity hair doesn’t need heavy oils; instead, use light, easily absorbed oils that lock in moisture without clumping your hair.

• 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 jojoba oil (for lightweight moisture)

• How to use it: Apply a few drops of oil or serum to your hair, focusing on the ends. Rub between your palms first, then smooth over your hair.

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

• What to Use: Use a lightweight heat protectant spray that can withstand temperatures of up to 450°F before blow drying or diffusing.

• How to use it: Use the lowest heat setting when blow-drying your hair to least 70% dry before using a straightener or other heating tools. If you style your hair frequently, use a silicone-free serum to reduce frizz and add volume. Protective styles like low buns, braids, or ponytails can reduce tangling and breakage.
