Absolutely, and for good reason! One of the goals of micro needling is to increase collagen in the scalp. Some chemical hair loss treatments are known to inhibit collagen production so it would be detrimental to apply it immediately after derma rolling. Plant oils, however, help with collagen production and can be used in conjunction with derma rolling, even helping prevent infection after derma rolling due to the antibacterial essential oils of lavender, cedar wood and rosemary.
