What’s inside — and why it’s there

Reviews
Questions? We get them.
Good to know.
The questions we hear most about this product. If yours isn’t here, a real stylist will answer.
Ask ModaIs the PhD Heat Styling Spray just a heat protectant?
No — it also adds the IQHC humidity defence and shine-enhancing properties, so it improves the finished style rather than just protecting during it.
When do I apply it?
To damp hair before blow-drying, or to dry hair before flat ironing or curling.
Is it suitable for fine hair?
Yes — the spray formula is lightweight enough not to flatten fine hair.
Is it suitable for damaged hair?
For heat protection on damaged hair it works, but pair it with the Restore Repair Leave-In for the repair benefit alongside the protection.
Is it colour-safe?
Yes.
