Putting a sodium hydroxide relaxer under a hair dryer can be a convenient way to speed up the drying process, but it’s important to be aware of the potential effects on your hair. In this article, we’ll discuss the chemical process of hair relaxing with sodium hydroxide, the effects of heat on relaxers, and the potential impact on hair health.
We’ll also provide guidelines for safe use of hair dryers with sodium hydroxide relaxers and offer alternative drying methods.
Sodium Hydroxide Relaxer Overview: Putting A Sodium Hydroxide Relaxer Under A Hair Dryer
A sodium hydroxide relaxer, also known as a lye relaxer, is a chemical treatment designed to straighten and smooth curly or coily hair. It contains sodium hydroxide (NaOH), a strong alkali that breaks down the hair’s disulfide bonds, allowing the hair to be reshaped into a straighter form.
The chemical process of hair relaxing with sodium hydroxide involves several steps. First, the relaxer is applied to the hair, where it penetrates the hair shaft and begins to break down the disulfide bonds. This process, known as hydrolysis, causes the hair to swell and become more pliable.
The hair is then rinsed and neutralized to stop the chemical reaction and restore the hair’s pH balance.
Potential Effects of Heat on Relaxer
Heat can significantly impact the performance and safety of sodium hydroxide relaxers. When heat is applied to a relaxer, it can accelerate the chemical reactions, leading to over-processing and potential hair damage.
- Increased chemical activity:Heat increases the rate of hydrolysis, causing the relaxer to work faster and potentially over-process the hair, resulting in breakage and dryness.
- Hair damage:Excessive heat can damage the hair’s cuticle, making it more prone to breakage and split ends. It can also lead to scalp irritation and burns if the heat is too intense or applied for too long.
Impact on Hair Health
Using a hair dryer on hair treated with a sodium hydroxide relaxer can have several potential consequences:
- Hair breakage:The combination of chemical processing and heat can weaken the hair shaft, making it more susceptible to breakage.
- Dryness:Heat can further dry out hair that has been chemically treated, leading to frizz, split ends, and a lack of shine.
- Scalp irritation:The heat from a hair dryer can irritate the scalp, especially if the hair is over-processed or the dryer is held too close to the scalp.
Recommended Precautions
To safely use a hair dryer with sodium hydroxide relaxers, follow these guidelines:
- Use a low heat setting:Avoid using high heat, as this can damage the hair and scalp.
- Hold the dryer at a distance:Keep the hair dryer at least 6 inches away from the hair to prevent overheating.
- Use a diffuser:A diffuser can help distribute heat evenly and reduce the risk of over-drying.
- Apply a heat protectant:Use a heat protectant spray or cream to shield the hair from heat damage.
Alternatives to Hair Drying, Putting a sodium hydroxide relaxer under a hair dryer
In addition to using a hair dryer with caution, there are alternative methods for drying hair treated with a sodium hydroxide relaxer:
- Air drying:Allowing the hair to air dry is the gentlest option, as it does not involve heat.
- Diffuser:Using a diffuser on a low heat setting can help reduce heat damage while still providing some styling.
- Towel blotting:Gently blotting the hair with a towel can help remove excess moisture without causing damage.
FAQ
Can I use a hair dryer on my hair after applying a sodium hydroxide relaxer?
Yes, but it’s important to use the correct temperature settings and application techniques to avoid hair damage.
What are the risks of using a hair dryer on relaxed hair?
Using a hair dryer on relaxed hair can increase the risk of hair breakage, dryness, and scalp irritation.
What are some alternative methods for drying relaxed hair?
Alternative methods for drying relaxed hair include air drying, using a diffuser, or using a towel to gently blot the hair.
