Sodium Hydroxide Relaxers Are Also Known As

Sodium hydroxide relaxers, often referred to as lye relaxers, stand as one of the most potent chemical treatments available for permanently straightening curly or kinky hair. These relaxers have been a staple in the African American community for generations, providing a means to achieve a smoother, more manageable hairstyle. However, the strength and effectiveness of sodium hydroxide relaxers also come with significant risks if not used correctly. Understanding the science behind these relaxers, the proper application techniques, and the necessary precautions is crucial for anyone considering this hair straightening method.

The Science Behind Sodium Hydroxide Relaxers

The active ingredient in lye relaxers is, as the name suggests, sodium hydroxide (NaOH). This compound is an incredibly strong alkali, also known as a base. The chemical action of sodium hydroxide on hair is what permanently alters its structure, resulting in a straightened appearance.

Hair's natural structure is primarily composed of a protein called keratin. Keratin molecules are linked together by various chemical bonds, including disulfide bonds, which are responsible for the hair's curl pattern. The more disulfide bonds present and the way they are arranged, the curlier the hair will be.

Sodium hydroxide relaxers work by breaking these disulfide bonds in a process called lanthionization. When the relaxer is applied to the hair, the high pH of the sodium hydroxide causes the disulfide bonds to break down and transform into lanthionine bonds. Lanthionine bonds are significantly more stable and resistant to reforming the original curl pattern. This chemical alteration is permanent, meaning that the hair that has been relaxed will remain straight, and only new hair growth will exhibit the natural curl pattern.

Identifying Sodium Hydroxide Relaxers

While "lye relaxer" is the common term for sodium hydroxide relaxers, it's important to be able to identify them on product labels. Here's what to look for:

• Ingredient List: The ingredient list will explicitly state "Sodium Hydroxide" as one of the primary components.
• Warning Labels: Products containing sodium hydroxide are required to have prominent warning labels about the potential for chemical burns, hair loss, and eye damage.
• Professional Use: Sodium hydroxide relaxers are often marketed for professional use only due to their strength and the precision required for safe application.

Why Choose Sodium Hydroxide Relaxers?

Despite the potential risks, sodium hydroxide relaxers remain a popular choice for several reasons:

• Effectiveness: They are incredibly effective at permanently straightening even the most resistant curl patterns.
• Speed: The straightening process is relatively quick compared to other methods, often taking less than 30 minutes.
• Long-Lasting Results: Once the hair is relaxed, it remains straight until new hair grows in, reducing the need for daily styling.

Potential Risks and Side Effects

The potency of sodium hydroxide relaxers means they come with a range of potential risks and side effects:

• Chemical Burns: The high pH of sodium hydroxide can cause severe chemical burns to the scalp and skin if the relaxer is left on for too long or if the scalp is not properly protected.
• Hair Damage: Overprocessing can lead to breakage, split ends, and severely weakened hair.
• Scalp Irritation: Even with proper application, some individuals may experience scalp irritation, redness, and itching.
• Hair Loss: In severe cases, improper use of sodium hydroxide relaxers can lead to hair loss, which may be temporary or permanent.
• Eye Damage: If the relaxer comes into contact with the eyes, it can cause serious damage, including blindness.

Alternatives to Sodium Hydroxide Relaxers

Given the potential risks, many individuals explore alternative hair straightening methods. These include:

• No-Lye Relaxers: These relaxers use different active ingredients, such as calcium hydroxide, guanidine hydroxide, or ammonium thioglycolate. While they are often marketed as being gentler than lye relaxers, they can still cause damage if not used correctly.
• Keratin Treatments: Also known as Brazilian blowouts, these treatments use keratin to temporarily straighten the hair. The effects typically last for several months, and the hair gradually returns to its natural curl pattern.
• Thermal Straightening: This method involves using heat styling tools, such as flat irons, to straighten the hair. While it is a temporary solution, it can cause heat damage over time.
• Texturizers: Texturizers are milder versions of relaxers that loosen the curl pattern without completely straightening the hair. They are a good option for those who want to reduce frizz and make their hair more manageable.
• Natural Hair Styles: Embracing natural hair textures through protective styles, such as braids, twists, and weaves, has become increasingly popular. These styles minimize manipulation and allow the hair to grow without chemical alteration.

Safe Application Techniques for Sodium Hydroxide Relaxers

If you choose to use a sodium hydroxide relaxer, it is crucial to follow these safety guidelines to minimize the risk of damage:

1. Perform a Strand Test: Before applying the relaxer to your entire head, perform a strand test to assess how your hair will react to the chemicals. This will help you determine the appropriate processing time and identify any potential problems.
2. Protect Your Scalp: Apply a base cream or petroleum jelly to your scalp and hairline to create a barrier between the relaxer and your skin. This will help prevent chemical burns and irritation.
3. Wear Gloves: Always wear gloves to protect your hands from the chemicals in the relaxer.
4. Follow Instructions Carefully: Read and follow the manufacturer's instructions precisely. Do not leave the relaxer on for longer than the recommended time.
5. Apply Correctly:
   • Virgin Relaxer: Apply the relaxer one-quarter inch away from the scalp down to the ends.
   • Retouch: Apply to new growth only, avoiding previously relaxed hair. Overlapping can cause breakage.
6. Smooth the Hair: Use the back of a non-metallic comb or your gloved fingers to gently smooth the relaxer through your hair. Do not pull or tug on the hair, as this can cause breakage.
7. Rinse Thoroughly: Rinse the relaxer out of your hair with cool water until all traces of the chemicals are gone. This may take several minutes.
8. Neutralize: Use a neutralizing shampoo specifically designed for relaxed hair to stop the relaxing process and restore the hair's pH balance. Follow the shampoo's instructions carefully.
9. Deep Condition: After neutralizing, apply a deep conditioner to replenish moisture and strengthen the hair. Leave the conditioner on for the recommended time, then rinse thoroughly.

The Role of a Professional Stylist

Given the complexity and potential risks associated with sodium hydroxide relaxers, it is highly recommended to have the treatment performed by a professional stylist. A trained stylist has the knowledge and experience to:

• Assess Your Hair Type and Condition: Determine if your hair is healthy enough to withstand a relaxer.
• Choose the Right Relaxer Strength: Select the appropriate strength of relaxer for your hair type and curl pattern.
• Apply the Relaxer Correctly: Ensure even application and proper processing time to minimize damage.
• Provide Post-Relaxer Care Instructions: Offer guidance on how to maintain the health and integrity of your relaxed hair.

Post-Relaxer Hair Care

After relaxing your hair, it is essential to follow a consistent hair care routine to maintain its health and prevent damage:

• Moisturize Regularly: Relaxed hair tends to be drier than natural hair, so it is crucial to moisturize it regularly with hydrating shampoos, conditioners, and leave-in treatments.
• Protein Treatments: Incorporate protein treatments into your routine to strengthen the hair and prevent breakage. However, avoid overusing protein, as it can make the hair brittle.
• Limit Heat Styling: Minimize the use of heat styling tools, such as flat irons and curling irons, as they can cause further damage to relaxed hair. When you do use heat, always apply a heat protectant spray.
• Wrap Your Hair at Night: Wrap your hair with a silk or satin scarf or sleep on a silk or satin pillowcase to prevent friction and breakage while you sleep.
• Trim Regularly: Trim your hair every 6-8 weeks to remove split ends and prevent them from traveling up the hair shaft.
• Avoid Overlapping: When retouching, apply the relaxer only to the new growth to avoid overlapping on previously relaxed hair.
• Use Sulfate-Free Products: Sulfates can strip the hair of its natural oils, leading to dryness and damage. Use sulfate-free shampoos and conditioners to maintain moisture.

Understanding Hair Porosity

Hair porosity refers to the hair's ability to absorb and retain moisture. Knowing your hair's porosity is crucial for choosing the right products and techniques for post-relaxer care.

• Low Porosity: Hair with low porosity has a tightly closed cuticle layer, making it difficult for moisture to penetrate. Use lightweight products that won't sit on the surface of the hair. Apply heat to help the hair absorb moisture.
• Medium Porosity: Hair with medium porosity has a slightly open cuticle layer, allowing moisture to penetrate and retain easily. This hair type is relatively easy to manage and style.
• High Porosity: Hair with high porosity has a very open cuticle layer, allowing moisture to absorb quickly but also lose it just as fast. Use heavier products to seal in moisture. Protein treatments can help to fill in the gaps in the cuticle layer.
