The TRESemmé Care & Protect Heat Defence Spray is designed to shield your hair from heat damage caused by styling tools like blow dryers, flat irons, and curling wands. With a 300ml bottle, it provides a good amount of product to protect your hair over time.

Key features typically include:
- **Heat Protection**: Helps prevent damage from high temperatures, maintaining your hair’s health.
- **Lightweight Formula**: Often designed to not weigh hair down or leave a greasy residue.
- **Smooth Finish**: Can help in reducing frizz and adding shine for a polished look.

To use, spray evenly on damp hair before styling, making sure to cover all areas. It’s a good idea to brush through to distribute the product evenly. This product can be a great addition to your hair care routine if you frequently use heat styling tools.
