A client asked: Why does your hair steam when using hot tools?

Last week a client mentioned that during a salon visit, when they were using a hot tool on her hair, there was steam. She wanted to know why this happened and should she be concerned. So, in this article, we’ll break down everything you need to know about heat styling and how to do it while protecting your hair. Let’s dive in!

Why does your hair steam when using a hot tool?

Hair is composed of proteins and moisture. When you apply heat, particularly high heat from styling tools like flat irons or curling irons, the heat causes the water molecules within the hair shaft to evaporate. This evaporation produces steam or vapor, which can be seen as the hair steaming.

3 reasons why you should be concerned?

Reason 1: Loss of moisture

Steaming is the result of losing moisture within your hair which increases the chance of drying out your hair over time.

Reason 2: Heat damage

Excessive heat can cause damage to the hair cuticle, which is the protective outer layer of each hair strand. When the cuticle is damaged, it can lead to moisture loss, hair breakage, split ends, and overall weakened hair structure. If you consistently use high heat without proper precautions, such as heat protectant products or adjustable temperature settings, it can significantly damage your hair over time.

Reason 3: Smoking hair

If you notice smoke coming from your hair while using heat styling tools, it is a more serious indication of potential damage. Smoking occurs when the heat applied to the hair is so intense that it can burn or singe the hair strands. This can result in irreversible damage, including hair breakage, thinning, and even a burnt smell.

Side note, if your hair is oily would that also cause steaming?

No, oily hair typically does not cause steaming when using heat styling products. The steaming effect is primarily caused by the evaporation of moisture from the hair shaft due to the application of heat. 

Oily hair occurs when the scalp produces an excess amount of sebum, the natural oil that helps moisturize and protect the hair. This excess oil can make the hair appear greasy and weighed down. However, it doesn't directly contribute to the steaming effect during heat styling.

Here are 5 tips to protect your hair when heat styling:

1. Use heat protectant products: Apply a heat protectant spray or serum to your hair before using any heat styling tools. These products create a barrier between your hair and the heat, reducing damage and moisture loss.

2. Lower the heat setting: Use the lowest effective temperature setting on your styling tools. High heat is not always necessary and can cause unnecessary damage. Adjust the heat based on your hair type and condition

3. Limit heat exposure: Minimize the frequency and duration of heat styling. Try incorporating heat-free styling techniques, like air-drying or using heatless curling methods, to reduce overall heat damage.

4. Opt for quality tools: Invest in high-quality styling tools that distribute heat evenly and have adjustable temperature settings. Cheaper tools may not regulate heat well, increasing the risk of damage.

5. Maintain hair health: Keep your hair well-moisturized and nourished by using hydrating shampoos, conditioners, and treatments. Regular trims to remove split ends can also help prevent further damage.
