1. Your hair feels coarse

Jack Cunningham-Rose, stylist and Pureology education

• “Coarse, rough strands can be a sign that hair is lacking moisture or hydration. If cuticle layers are raised, the hair can look and feel coarse.”
  
• “Color Fanatic Multi-Tasking Leave-In Spray treatment contains ingredients such as camelia oil and olive oil which help to replenish lost moisture, hydrate and smooth hair.”
  

2. Your scalp is dry and flaky

Victoria Panting, Paul Mitchell technical educator

• “A dry or flaky scalp is caused when the glands that produce natural oils are not working as they should be and are dehydrated.”

• “Clean Beauty Hydrate adds moisture and soothes the scalp. Olive helps lubricate and condition the hair with high quantities of oleic acid, squalene and phytosterols.”

3. Your hair looks dull

Jimmy Green, Redken education manager

• “The lipid area of hair is responsible for holding moisture, softness and shine. When hair is dehydrated, this results in a dull, lacklustre, tired look.”
• “Formulated with hyaluronic acid, this leave-in treatment works by trapping moisture molecules and sealing the cuticle barrier with an acidic pH to retain moisture."

4. You have split ends

Philip Downing, Bed Head creative director

• “Split ends can occur due to dry, brittle, over-processed hair. Overuse of heated appliances can also contribute to split or frayed ends.”
• “Ego Boost contains an effective conditioning complex of hydrolysed keratin and hydrolised silk. This reduces frizz, restores healthy condition back into the hair.”

5: Your hair feels brittle

Jacopo Grazzi, Product Manager

• “Brittle, damaged hair can be a sign that hair lacks moisture for a variety of reasons. Hair can naturally be prone to dryness or it can be because of aggressions such as heat or chemicals.”
  
• “Absolut Repair 10 in 1 Leave in Oil contains Wheat Germ oil to deeply hydrate the hair, boost shine and leave strands feeling softer."
