What Do I Need to Know About Permanent Hair Straightening Side Effects?

What is Permanent Hair Straightening?

Permanent hair straightening, also known as hair relaxing, is a popular method of permanently straightening the hair.

It is a process that involves the application of chemicals, such as lye or ammonium thioglycolate, that break down the bonds in the hair in order to make it straight.

While it produces smoother, straighter hair for many, there are also potential side effects to consider before selecting this option.

How Many Side Effects Can There Be?

It is important to understand the potential permanent hair straightening side effects prior to undergoing this procedure, whether the treatment is going to be done at home, or on a client.

As a stylist you must inform clients of the potential long-term effects of permanent hair straightening and advise them to seek medical advice if there are any concerns.

• Scalp Irritation

The most common permanent hair straightening side effect is scalp irritation. This is caused by the chemical being applied to the scalp, which can cause burning, itching and redness.

• Dry, Flaky Skin

If the chemical comes in contact with the scalp, it can damage the protective layers of the scalp, which can lead to flaky, irritated skin.

• Chemical Burns

Long-term contact with the chemicals used in permanent hair straightening can cause permanent damage to the scalp such as chemical burns.

• Hair Loss

Another side effect of permanent hair straightening is hair loss. This can occur due to the stress of the procedure itself, as well as possible scalp irritation due to the chemicals used.

It is important for clients to discuss their medical history and any existing hair loss conditions with their professional hairstylist or physician prior to undergoing the procedure.

• Hair Dryness

Permanent hair straightening has been linked to increased hair dryness.

The chemicals used in the procedure can cause the hair to become dry, brittle, and break easily. This can lead to split ends, which can make hair more difficult to manage and style. It is important for clients to discuss the necessity of using appropriate hair care products with their professional hairstylist or trichologist prior to undergoing the procedure.

• Breakage

Damage resulting in breakage is another potential side effect of permanent hair straightening.

• Thinning & Frizziness

The chemicals can cause permanent damage to the hair strands, as a result of breakage, thinning, and frizziness.

Additionally, the hair can become more susceptible to styling damage, as the tools used to style hair can cause more damage to already weakened hair strands.

Evidence Behind Chemical Hair Straightening and Cancer?

Hair straightening treatments, specifically formalin-based products, are thought to be a potential cause of cancer.

However, there is conflicting evidence regarding the link between chemical hair straightening and cancer.

As such, questions remain as to whether or not chemical hair straightening actually causes cancer.

Here, we’ll discuss the evidence behind the theory that chemical hair straightening can cause cancer.

First, it’s important to understand what is meant by “chemical hair straightening”.

Chemical hair straightening typically involves a range of formalin-based products, such as the Brazilian keratin treatment (BKT), which contain amino acids, formaldehyde, and other substances.

These products are designed to help smooth and straighten hair.

What is Formalin?

Formaldehyde is a known carcinogen (a substance that causes cancer). It is also an eye, throat, nose, and skin irritant.

Formaldehyde can be found in many household products, such as glues, lacquers, and paints, and is also used as a preservative in many hair-straightening products.

Does Formalin Cause Cancer?

The answer to this question is not a straightforward one. Although formaldehyde is known to be a carcinogen, studies have not yet been able to clearly establish a link between chemical hair straightening and an increased risk of cancer.

Studies conducted on animals have suggested that formaldehyde exposure is linked to the development of various cancer types, including leukemia, lymphoma, and bladder cancer.

It is important to note, however, that studies conducted on animals do not necessarily translate to a connection in people.

Studies conducted on humans have not been able to conclusively link formaldehyde exposure to an increased risk of cancer.

For instance, a 2010 study conducted in Brazil examined the link between BKT exposure and leukemia risk. The study did not find an increased risk of leukemia in individuals who had received BKT.

In addition, a 2018 review of existing studies on the link between chemical hair straightening and cancer concluded that there wasn’t enough evidence to clearly establish a link between the two. The authors argued that further evidence was needed in order to make an accurate assessment of the potential risks associated with chemical hair straightening treatments.

At present, the evidence around the potential link between chemical hair straightening and cancer is inconclusive.

Can Hair Straightening Damage your Hair?

Permanent hair straightening is a process that involves the use of chemical or thermal treatments to permanently transform naturally curly or wavy hair into straight shiny hair. It may sound like the perfect solution for your hair woes, but permanent hair straightening can come with a few serious drawbacks.

As a professional in the field of hairstyling, it is important and necessary to advise clients about the risks associated with Permanent hair Straightening before the service has begun.

It is important to keep the hair hydrated and nourished in order to prevent damage and hair loss.

Another major risk associated with Permanent Hair Straightening is that it can weaken the hair. The use of strong chemicals can cause the hair to lose its natural elasticity and consequently, become more prone to breakage.

Hair that has undergone the process may also be harder to color or curl as the chemicals used may interfere with the ability of the hair to hold product and styles due to cuticle damage.

Additionally, the risk of hair loss is a real concern for people who have undergone permanent hair straightening treatments. The chemical and thermal treatments can strip away the hair’s natural oils and weaken the hair’s roots making it prone to breakage and hair fall.

How to Treat Damage from Permanent Hair Straightening

It’s difficult sometimes to balance between beauty and well being.

And considering the potential consequences of chemical hair straightening when that balance is off.

As a hair professional, your clients often come to you with a specific goal or vision for their hair, so it is your responsibility to ensure they understand the risks and have realistic expectations.

Properly determining the course of action for each individual is paramount, as each person’s hair and body is unique and may respond differently to the same processes.

Here are a few steps that can be taken to treat hair damage from chemical hair straightening:

1. Proper Product Selection and Application

Many clients come to you for chemical hair straightening because they want a smooth and sleek look. Choosing the right product is essential, as the chemicals used will affect the health of the hair. Make sure to use products specifically designed for that purpose, to avoid damage and ensure lasting results.

Also, be sure to follow the product’s instructions as closely as possible. This will minimize the potential for damage and increase the effectiveness of the product.

If unsure of what the best product for a specific client is, consult with another stylist or mentor who is experience and familiar with the different permanent straightening brands, processes, and techniques, who has the training and experience to address individual needs.

2. Hair Preparation and Protection

Prior to chemical hair straightening, hair should be thoroughly washed and treated with a protein-enriched pre-conditioning treatment.

This treatment will ensure the hair is strong and healthy, and less prone to damage during the chemical process. Additionally, it is important to apply a heat protectant aerosol before straightening to further guard against heat damage.

This product will create a barrier between the heat and your clients’ hair, helping to lock in moisture and provide extra protection during styling.

3. Hydration and Care

Chemically straightened hair is more fragile, therefore proper hydration and care must be part of your client’s daily routine.

Once the straightening process is complete it is essential to immediately treat the hair with a repairing and hydrating mask, such as one specifically formulated for chemically treated hair.

This will ensure the hair is strong and soft while providing the necessary hydration. Throughout the day, a light spray or leave-in conditioner may be used to lock-in moisture.

4. Gentle Styling

Instead of relying on daily heating tools, encourage your clients to use styles that require less manipulation.

These could include protective styles such as –

• Buns
• Ponytails
• Or Braids

All of which are less damaging.

Additionally, methods such as air drying and towel drying can be done, versus blow-drying or straightening the hair with a flat iron.

Regular trims will help keep your client’s hair healthy and looking beautiful. Hair that has been chemically straightened will require more frequent trims due to split ends.

For every 3-4 months, or once per season (Winter, Summer, Spring, and Fall) opt for a “dusting”, which means just snipping off the split ends. This will help minimize overall damage and keep the hair looking healthy.

Do Split Ends Stop Hair Growth?

Make sure to adequately explain the risks to your clients and emphasize the importance of staying proactive in maintaining hair health.
