Hair Relaxer: Everything You Need to Know

Hair relaxers have been a staple in the beauty industry for many years, offering a way to straighten curly, wavy, or frizzy hair. They work by chemically altering the natural structure of the hair to make it smoother, straighter, and more manageable. If you’re considering using a hair relaxer or simply want to learn more about it, you’re in the right place. This article will guide you through everything you need to know about hair relaxers: how they work, different types, their benefits, risks, how to apply them, and the aftercare needed to keep your hair looking its best.

What is a Hair Relaxer?

A hair relaxer is a chemical treatment used to straighten curly or wavy hair. It breaks down the natural curl pattern of the hair, allowing it to lie flat and appear smoother. These products are often used by people with naturally curly or coily hair who desire a straighter look.

Hair relaxers are formulated with chemicals that break the disulfide bonds in the hair’s cortex (the inner layer). These bonds are what give hair its natural texture. When the bonds are broken, the hair loses its curl, resulting in smoother, straighter strands.

Types of Hair Relaxers

There are several types of hair relaxers, each with its own benefits and considerations. These are:

1. Lye Relaxers

Lye relaxers are the most common and potent type of relaxer. They contain sodium hydroxide, a strong chemical that quickly and effectively straightens the hair. However, lye relaxers can be harsh on the scalp, so they must be applied carefully.

Pros:

• Effective for coarse and resistant hair.
• Provides long-lasting results.

Cons:

• Can cause scalp irritation if not applied correctly.
• Requires professional application in many cases.

2. No-Lye Relaxers

No-lye relaxers, as the name suggests, do not contain sodium hydroxide. Instead, they use calcium hydroxide or guanidine hydroxide. These relaxers are generally gentler on the scalp and less likely to cause irritation.

Pros:

• Gentler on the scalp.
• Suitable for sensitive skin.

Cons:

• Not as effective on very coarse or resistant hair.
• Can cause hair to become dry or brittle if not properly cared for after treatment.

3. Thio Relaxers

Thio relaxers contain ammonium thioglycolate, a chemical that alters the disulfide bonds in the hair in a way similar to perming solutions. Thio relaxers are a gentler option than lye relaxers but are still potent enough to straighten even the most stubborn curls.

Pros:

• Less irritating to the scalp than lye relaxers.
• Effective for all hair types.

Cons:

• Can cause hair damage if overused.
• Requires more careful application than other types.

4. Keratin Relaxers

Keratin relaxers are considered a “semi-permanent” option that not only straightens hair but also improves its health. These products contain keratin, a protein that strengthens hair, as well as formaldehyde or formaldehyde-releasing ingredients to straighten hair.

Pros:

• Provides smooth, shiny results.
• Strengthens hair and reduces frizz.

Cons:

• Formaldehyde is a controversial ingredient due to health concerns.
• Results may not be as long-lasting as with traditional relaxers.

Benefits of Hair Relaxers

There are several reasons people choose to use hair relaxers, and each person’s reasons might be different. Here are some common benefits:

1. Long-Lasting Straightening

Hair relaxers provide long-term straightening results, unlike temporary solutions like flat ironing or blow-drying. Once applied, hair remains straight for several weeks, saving time on styling.

2. Easier Hair Maintenance

For individuals with naturally curly or wavy hair, hair relaxers make daily hair maintenance easier. With relaxed hair, there is less frizz, tangling, and curling, reducing the amount of time spent styling each day.

3. Smooth, Shiny Hair

Relaxers can make hair look smooth, shiny, and healthy. The straightened hair reflects light better, creating a polished and sleek look.

4. Versatile Styling

With relaxed hair, styling options become more versatile. Straight hair allows for different hairstyles, including updos, sleek ponytails, and a variety of textures that may be difficult to achieve with naturally curly or coarse hair.

Risks and Side Effects of Hair Relaxers

While hair relaxers can provide a beautiful, sleek look, they come with some risks that need to be considered before use. Here are the main risks:

1. Hair Damage

One of the biggest concerns with hair relaxers is hair damage. The chemicals used to break the disulfide bonds in hair can weaken the strands, leading to breakage, dryness, and thinning. It’s essential to follow aftercare routines to minimize damage.

2. Scalp Irritation

The chemicals in hair relaxers, especially lye-based ones, can cause irritation or burns to the scalp if left on too long or if not applied correctly. Always perform a patch test before applying any relaxer to your hair.

3. Health Concerns

Some hair relaxers, particularly those containing formaldehyde or formaldehyde-releasing chemicals, have raised health concerns. Prolonged exposure to formaldehyde has been linked to respiratory issues and even cancer in some cases. It’s important to use products that are safe and follow all safety precautions during application.

4. Uneven Results

If not applied correctly, hair relaxers can lead to uneven results. Some areas of the hair may remain curly, while others may become excessively straight. This can be frustrating and requires a professional’s touch for the best results.

How to Apply a Hair Relaxer

Applying a hair relaxer requires precision and care. While some people choose to do it themselves, it’s generally recommended to visit a professional stylist to avoid mishaps. Here’s a general overview of how a hair relaxer is applied:

1. Preparation

Before applying the relaxer, it’s important to prepare the hair. Wash your hair with a clarifying shampoo to remove any buildup, but leave it slightly damp. Protect your scalp by applying a barrier cream around the hairline to prevent chemical burns.

2. Application

Divide your hair into sections, and apply the relaxer to each section, starting from the back. Make sure the relaxer is evenly distributed throughout the hair, using a comb to smooth it through. The application process should be quick, as the relaxer starts working immediately.

3. Processing Time

Allow the relaxer to process for the recommended time, usually 10 to 20 minutes, depending on the type of relaxer and the hair’s thickness. Do not exceed the recommended time, as this could cause damage.

4. Rinsing and Neutralizing

Once the relaxer has processed, rinse it thoroughly with warm water to remove all the product. Follow up with a neutralizing shampoo to stop the chemical process and restore the pH balance of the hair. Conditioning treatments are essential at this stage to restore moisture.

5. Aftercare

After the relaxer is applied, it’s crucial to keep the hair hydrated. Use moisturizing shampoos, deep conditioners, and leave-in treatments to maintain hair health. Regular trims can help prevent split ends and breakage.

Aftercare for Relaxed Hair

Taking care of relaxed hair is essential to maintaining its health and appearance. Here are some tips for aftercare:

1. Moisturize Regularly

Relaxed hair tends to lose moisture more easily, so moisturizing is crucial. Use leave-in conditioners, oils, and deep conditioning treatments to keep the hair hydrated.

2. Avoid Heat Styling

Excessive heat can further damage relaxed hair. Minimize the use of flat irons, curling irons, and blow dryers. If you must use heat, always apply a heat protectant.

3. Trim Regularly

To prevent breakage and keep the hair looking healthy, trim relaxed hair every 6 to 8 weeks. This will help to remove split ends and maintain a fresh, neat appearance.

4. Protect Your Hair While Sleeping

Use a satin or silk scarf or pillowcase to protect your hair while you sleep. These materials reduce friction, preventing breakage and frizz.

5. Use Sulfate-Free Products

Sulfates can be drying and strip moisture from relaxed hair. Use sulfate-free shampoos and conditioners to preserve moisture and prevent hair damage.

Alternatives to Hair Relaxers

If you’re not keen on using chemical relaxers, there are alternative options for straightening curly hair. These include:

• Keratin treatments: Offer smoother hair with less frizz.
• Blowouts and flat irons: Temporary methods for straightening hair without chemicals.
• Natural oils and treatments: For controlling frizz and maintaining curl definition.

Conclusion

Hair relaxers are a powerful tool for straightening curly or wavy hair. Whether you choose a lye relaxer, no-lye relaxer, or keratin-based option, the benefits include smoother, more manageable hair with long-lasting results. However, it’s important to understand the risks involved, including potential hair damage and scalp irritation.

By following the proper application techniques and aftercare routine, you can enjoy healthy, beautiful relaxed hair. If you’re considering using a relaxer, make sure to do thorough research or consult a professional stylist to ensure you’re using the best product for your hair type.

With the right care, relaxed hair can look fantastic and be easier to manage, allowing you to express your personal style with confidence!
