Whenever Dr. Lamm is asked to choose her favorite hair growth oil, she undoubtedly selects rosemary oil each time. “It stands out as one of the most remarkable essential oils in research, and its extensive benefits include the prevention of hair loss, the promotion of blood circulation, the stimulation of hair regeneration, as well as the effective control of itching and pore unclogging,” says Dr. Lamm. One of the beauty market’s most coveted rosemary oils is this Mielle Organics oil, which works as an intensive deep treatment to prevent damage and promote hair growth. This biotin-infused blend also promotes circulation in the scalp and helps to combat dandruff. However, Dr. Zion notes that pregnant women should avoid rosemary oil due to its potency.
