Glycerin soap makes a great alternative for shampoo. In this article, we discuss the benefits of using glycerin soap for hair, particularly for those with sensitive skin.

People have been using glycerin to make soap since the mid-nineteenth century. It makes a gentle, mild, and moisturizing cleanser, and with the many benefits it provides, its popularity is likely to continue to grow.

So, are there proven benefits of using glycerin soap for hair?

Glycerin soap for hair is an excellent alternative to shampoo. Glycerin soap is great for sensitive skin, which harsh shampoo chemicals can sometimes trigger. If you have dry hair, glycerin soap helps protect the hair’s natural oils and retains moisture, meaning you won’t get oily hair or dandruff.

What Is Glycerin?

Glycerin is a colorless, odorless liquid derived from plant-based oils, animal products, or petroleum.

It’s a humectant, which is a common moisturizing agent typically found in hair and skin products such as shampoos and lotions.

Humectants retain moisture while preserving other properties of the product.

Hair and skin products that contain glycerin usually contain occlusives, which is another moisturizing agent.

Occlusives form a protective layer that acts as a barrier to prevent the moisture from escaping.

What Is Glycerin Soap?

Glycerin soap is a gentle, moisturizing cleanser. It is usually clear and transparent, and can be used on all skin types.

Many over-the-counter (OTC) soaps contain ingredients like alcohol and fragrances that can irritate your skin.

Glycerin soap is all-natural which makes it great for people who have sensitive skin.

Using hot water or harsh products on your hair and skin and can strip any natural oils away, and you may experience conditions such as dry skin, eczema, psoriasis, rosacea, or acne.

Glycerin soap helps your hair and skin lock in moisture and can stop the skin from becoming overly dry.

As glycerin soap is non-greasy, people who have oily or combination skin can also benefit from using it.

Benefits Of Using Glycerin Soap For Hair

Glycerin soap has many benefits for your skin, which is why it is used as a key ingredient in many skincare products. But it can also be beneficial for you to use on your hair.

Here are some of the benefits of using glycerin soap for hair:

Protects The Hair’s Natural Oils

Some shampoos can strip the hair of its natural oils, leaving the hair and scalp feeling dry.

Glycerin soap helps retain moisture, so when you wash your hair with it, it removes the dirt but leaves the hair feeling well-nourished.

Free Of Sulfates

Some drugstore shampoo brands contain harmful chemicals that can strip the color away from the hair.

Chemicals like Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) can irritate the skin, eyes, and lungs.

Glycerin soap is made out of all-natural sources and is free of any toxic sulfates.

Helps Seal In Moisture

Glycerin is well-known for its moisturizing qualities.

If you have dry hair, consider using glycerin soap to help seal in the moisture. Because glycerine is a humectant, it’s good at pulling moisture from the air and retaining it.

Your hair will no longer feel dry. Instead, you’ll notice it looking more hydrated and feeling softer and smoother.

Doesn’t Leave A Residue

Many shampoos can leave a residue in your hair and on your scalp over time. Shampoos that contain waxes or synthetic silicones can leave your hair looking flat, dull, with no shine even after you have washed it.

This can then clog up your hair follicles resulting in an itchy scalp. Glycerin soap rinses away quickly and easily without leaving any residue on your hair or scalp.

Relieves Dry, Flaky Scalp

If you have a dry, flaky scalp, using a glycerin soap can help relieve the symptoms.

Some people find that some anti-dandruff shampoos don’t work as well as they should, which can be frustrating.

Glycerin soap locks in moisture and prevents the skin from becoming dry. Try using glycerin soap alternatively with anti-dandruff shampoo to see results.

Signs You Could Benefit From Using Glycerin Soap

If you’ve never used glycerin soap on your hair before, you may be unsure if you actually need to use it.

However, there are some signs you should look out for that will help you decide if you need to use glycerin soap on your hair or not.

Let’s take a look.

Your Anti-Dandruff Shampoo No Longer Works

When you use specific hair products on your hair for a long time, your hair becomes accustomed to the product. This can result in the product becoming somewhat ineffective.

If you experience dandruff and notice that your anti-dandruff shampoo no longer works, it may be time to use glycerin soap on your hair instead.

Glycerin soap can help give your scalp the moisture that it has been lacking. Use it alternatively with your anti-dandruff shampoo to see an improvement.

Your Hair Is Damaged And Breaks Off

Glycerin soap can help condition your hair and give it the nourishment it needs.

If your hair is in bad condition and breaks off easily, you need to use a product that will strengthen the hair.

Using glycerin soap for hair can condition and strengthen it to become less prone to split ends.

Your Hair Looks Flat And Dull

When your hair starts to look flat or dull, you likely have a build-up of product on your hair and scalp.

No matter how much you try to wash it off, it just won’t budge. This can cause hair follicles to become blocked and inflamed, causing irritation.

Gently lather glycerin soap into your hair and scalp to remove the build-up residue, and you will soon begin to notice your hair looking and feeling completely different.

When Shouldn’t You Use Glycerin?

Although glycerin soap is safe to use on all hair types and has many proven benefits, some people may still have concerns about using it.

Here are some considerations you should keep in mind when using glycerin on your hair:

  • If you have any cracked or broken skin on or around your scalp, do not use glycerin.
  • Do not use glycerin if you have an allergy to it. If you are unsure, always do a patch test beforehand to determine if you have an allergy.
  • Some climates can prevent glycerin from working properly. If the environment around the hair is drier than the hair, it may try to balance the moisture in the atmosphere by releasing moisture back into the air.

If you think that glycerin may cause more harm than good, try these glycerin-free hair products.
