How Does a Blow Brush Work?

How to Use the Blow Brush Settings Properly

First, understand one thing clearly.

A blow brush has two jobs, done in order:

• Dry the hair
• Shape the hair

These two jobs do not happen on the same setting.

Before we talk about settings, there is one foundational principle most people miss.

foundational principle most people miss

Blow drying is not the act of styling dry hair.

Blow drying is the act of drying wet hair while moulding it into shape.

This is why every professional stylist always starts with:

• wet hair
• or evenly damp hair

Never bone-dry hair.

Water is not the enemy during blow-drying.

Water is the medium that allows hair to change shape safely and predictably.

When hair contains moisture:

• heat softens the internal structure evenly
• airflow guides the strand while it is flexible
• the shape forms as water leaves the fibre

When hair is already dry:

• heat has nothing to soften
• airflow only agitates the surface
• friction increases
• stress increases
• results drop faster

Blow drying dry hair is stressful for the strand.

It is like trying to mould metal when it is cold instead of hot.

The ideal starting state

• Hair washed
• Excess water removed with a towel
• Damp, not dripping
• Even moisture throughout the head

Towel logic matters

• Dab first to remove excess water
• Scrub gently to remove surface moisture
• Do not leave hair soaked
• Do not let hair dry completely before styling

Although a blow brush can be used on damp hair, dry hair, or hair washed days ago, the best, cleanest, longest-lasting blowouts happen when:

• hair starts damp
• moisture exits gradually
• shaping happens during drying

This is not preference.

This is physics.

If you remember only one thing:

You are not styling hair after it dries.

You are styling hair while it dries.

Now, with that foundation clear, the settings will make sense.

STEP 1: Preparation (Setting 1: High Air + Low Heat)

What this stage is for

This stage is only about removing moisture and preparing hair to be shaped.

What Setting 1 actually does

• High airflow dries hair quickly
• Low heat keeps hair safe during drying
• Hair becomes dry, warm, and ready to mould

What Setting 1 does NOT do

• It does not create volume
• It does not lock shape
• It does not finish styling

How long to use it

• Until hair is fully dry
• Hair should feel warm, not hot

Most common mistake at this stage

Trying to style on Setting 1

This causes frizz, collapse, and short-lasting results.

STEP 2: Choose ONE Styling Setting. THIS DECISION MATTERS

Once hair is dry, choose one styling setting based on hair type.

Do not keep switching settings.

Option A - Setting 2 (Medium Air + High Heat)

Who this is for

• Straight hair
• Medium hair
• Medium to thick wavy hair

Why this setting works

• High heat makes hair mouldable
• Medium airflow keeps hair controlled
• Hair stays aligned instead of flying around

What results this setting gives

• Smooth blowouts
• Soft volume
• Better hold

How to use it properly

• Work in controlled sections
• Use slow, steady brushing
• One clean pass per section

Common mistake

Switching to Setting 3 even when hair doesn’t need it.

Option B - Setting 3 (High Air + High Heat)

Who this is for

• Thick hair
• Coarse hair
• Curly or stubborn hair
• Hair that resists shape

Why this setting exists

• Dense hair needs more heat to mould
• Strong airflow helps heat reach through thick sections
• Tension and heat work together here

What results this setting gives

• Faster shaping
• Cleaner results in fewer passes
• Less need for correction

How to use it properly

• Smaller, controlled sections
• Slow movement
• Do not rush

Common mistake

Using this on fine or fragile hair unnecessarily.

very important rule which most people miss

• Use Setting 1 only for drying
• Choose either Setting 2 or Setting 3 for styling
• Finish the entire blowout on the same styling setting

Switching settings mid-style:

• breaks consistency
• increases frizz
• reduces hold

If your blowout doesn’t last, check this in order

• Was hair started damp and dried properly?
• Was hair fully dry before styling?
• Was the correct setting chosen for hair type?
• Were sections controlled and slow?

In most cases:

• The brush is fine
• The hair is fine
• The problem is choice and use of blow brush settings
