Wet Brush Go Green Detangler (£15) is a practical, pretty, and sustainable gift — what's not to love? The Go Green collection is made from PLA (plant-based plastic), using 65 percent less energy used, 68 percent less greenhouse gas, and promises to naturally biodegrade in 5 years once thrown away. The brushes are suitable for all hair types and textures, as well as extensions and wigs.
