On 19 July, The Hair Lab by Mark Hill introduces a range of products at Boots aimed at repairing the internal bonds of your hair. With the goal of leaving strands stronger, softer, shinier, and more resilient, the Bond Repair range includes shampoo, conditioner, a leave-in styling cream, and The Hair Lab by Mark Hill Bond Building Treatment (£20), which is the heavy hitter of the group. The super-concentrated cream gets applied to towel-dried hair and left on for 10 minutes before getting washed out and should be used once or twice a week depending on how damaged your hair is. Using it regularly will ensure that your hair stays in top shape regardless what you put it through.
