Steps on how to properly use a diffuser on straight hair

Step 1: Wash and Brush your hair

We always recommend washing your hair before using a hair dryer. This is because you should never use your hair dryer on a dry hair and risk damaging it. While your at it you should also use a straightening shampoo and conditioner. We recommend that you buy a sulfate-free shampoo because this tends to be much gentler to your hair.

After your shower, use a wide-tooth comb to detangle your hair, this would be beneficial later on because you don’t want your hair to get caught on the spikes of the diffuser.

You should also dry your hair using a towel to about 60 percent. And if possible use a microfiber towel if you have one. Microfiber towels tend to reduce the chance of frizz from our experience.

Step 2: Apply a heat protectant product

Use a heat protectant product to minimize the chance of heat damage. We recommend that you look for a silicon-based heat protectant as they tend to be much better at protecting your hair from heat damage. This provides an extra barrier between your hair and the heat to further reduce the chance of heat damage.

Step 3: Diffuser time!

Place the diffuser on one side of your head near the roots by tilting your head. Then move the diffuser in a circular motion. After that section is dry, you can move to the next section of your hair and repeat the process of doing a circular motion. 

We recommend that you use the lowest setting possible to reduce that chance of heat damage. This might be slower but it’s better to be safe than sorry!

Step 4: Mist it to style it!

Apply some products like oils and finishing serums to lock in the style and add additional shine to your hair.
