Aromatherapy moisturizing hair essential oil is a hair care composition without silicone oil, which has both scalp care and sun protection functions. The commonly used chemical synthetic silicone oil is replaced by natural plant oils such as olive oil, jojoba oil, thorn dry tree kernel oil, sunflower seed oil, ginger oil, and natural plant essential oils such as lavender essential oil, rosemary essential oil and bergamot essential oil. the smaller molecular structure enables it to go deep into the scalp and hair core to repair, and at the same time, it can also form a water-locking film on the surface of the hair to repair the hair from the inside out. In addition, the natural essential oil can effectively relieve pressure while repairing hair. Sunscreen ingredients such as ethyl hexyl methoxy cinnamate and chamomile extract can effectively absorb ultraviolet rays and reduce the damage caused by ultraviolet radiation.
