What is Glycerin?

Glycerin, also known as glycerol, is a colorless liquid derived from animal fat or vegetable oils.

It’s a natural compound and a sugar alcohol with exceptional humectant properties, making it a common ingredient in beauty products, including hair care products.

Benefits of Glycerin

Glycerin is renowned for its hydrating and moisturizing capabilities, which make it an effective ingredient for various hair concerns.

Here are some of the main benefits of glycerin:

  • Hydration: As a natural humectant, glycerin draws moisture from the environment into the hair shaft, ensuring your hair stays hydrated, especially in a dry climate.
  • Scalp Health: Glycerin helps maintain a healthy scalp environment by preventing dryness and reducing itchiness.
  • Strengthens Hair: By improving the hydration of hair strands, glycerin reduces hair breakage and prevents split ends, promoting overall hair health.
  • Enhances Hair Growth: A well-hydrated scalp can improve the condition of hair follicles, leading to healthier hair growth.
  • Reduces Frizz: Glycerin helps manage frizzy hair by locking in moisture, making it an excellent ingredient for those with curly hair or high porosity hair.
  • Versatility: Glycerin can be used in various DIY hair masks, leave-in treatments, and homemade hair products, making it a flexible addition to your hair care routine.

Is Glycerin Good for Your Hair?

Yes, glycerin is good for your hair. Its humectant properties make it highly effective in drawing and retaining moisture, which is essential for maintaining healthy hair and scalp.

A small study demonstrated that glycerin is a humectant that attracts, binds, and retains moisture. It can easily absorb excessive moisture.

Glycerin and Hair Types

Glycerin benefits a wide range of hair types, but its effectiveness can vary based on individual hair characteristics:

  • Curly Hair: Glycerin works wonders for curly hair by maintaining moisture and reducing frizz.
  • Dry Hair: For those with dry hair, glycerin’s hydrating properties are particularly beneficial, helping to combat brittleness and dehydration.
  • High Porosity Hair: Glycerin is excellent for high porosity hair, which tends to lose moisture quickly, as it helps retain hydration.
  • Sensitive Scalp: Those with a dry or itchy scalp can benefit from glycerin’s soothing and hydrating effects.

While glycerin is great on basically all hair types, these are the main hair types that benefit, majorly from using glycerin.

How To Use Glycerin for Your Hair

There are different ways to incorporate glycerin into your hair care routine. Here are some of the most effective methods:

DIY Hair Spray (Leave-In)

A DIY glycerin hair spray is a great leave-in conditioner that keeps your hair hydrated throughout the day.


  • 1 cup of water
  • 2 tablespoons of vegetable glycerin
  • 1 tablespoon of rose water
  • 1 tablespoon of aloe vera gel
  • 5-10 drops of your favorite essential oil (optional), I like to add peppermint and rosemary essential oils.

How To Make Your DIY Hair Spray:

1. Combine glycerin, rose water, and aloe vera gel in a spray bottle.

2. Add water and essential oil (if using) and shake well.

3. Spray on damp hair, focusing on the ends of your hair.

Glycerin is great as a leave-in treatment, but it can also be great as a styling spray, here is how to use it in a DIY Sea Salt Spray for Turning Fine Hair To Beachy Waves.

    A DIY hair mask with glycerin can deeply nourish and condition your hair.


    • 2 tablespoons of vegetable glycerin

    1. Mix all ingredients until well combined.

    2. Apply to damp hair, covering from roots to tips.

            Tips for Using Glycerin in Your Hair

            To get the most out of glycerin in your hair care routine, follow these tips:

            • Patch Test: Before using glycerin, perform a patch test to check for any allergic reactions.
            • Use a Small Amount: Start with a small amount to see how your hair responds.
            • Combine with Other Ingredients: Mix glycerin with other natural ingredients like coconut oil, aloe vera gel, or castor oil for enhanced benefits.
            • Avoid Overuse: Using too much glycerin can lead to buildup, so use it sparingly.
            • Humidity Considerations: Glycerin works best in moderate humidity. In very dry or very humid conditions, it may not be as effective.

            When to Avoid Using Glycerin

            While glycerin is generally safe, there are times when you should avoid using it:

            • Allergic Reaction: If you experience any side effects, discontinue use immediately.
            • Dry Climate: In extremely dry climates, glycerin can draw moisture away from the hair, leading to dryness and brittleness.
            • High Porosity Hair in High Humidity: In very humid conditions, glycerin can make high porosity hair frizzier.

            Glycerin is a powerful and versatile ingredient in hair care, offering numerous benefits from hydration to improved scalp health.

            Whether you have dry hair, curly hair, or high porosity hair, glycerin can be a great addition to your hair care routine.

            By using glycerin in DIY hair sprays, masks, conditioners, and pre-poo treatments, you can achieve healthier, more manageable hair.

            Always remember to use it in moderation and consider the humidity and climate conditions for the best results.

            With the right approach, glycerin can be your go-to ingredient for achieving and maintaining beautiful, healthy hair.
