How often should I oil my scalp with braids, considering the various factors that may influence this critical aspect of hair care? Could the frequency of oiling depend on the texture and type of my hair, or perhaps the specific style of braiding that I have chosen? Is there a difference in oiling practices for tight braids versus loose ones? Furthermore, how do environmental elements, such as humidity and exposure to sun or pollution, affect the overall health of my scalp when it is braided? Should I be attentive to the signs of dryness or irritation, and how might those indicators signal the need for more regular oil application? Additionally, could the choice of oil play a significant role in determining how frequently I should attend to my scalp? Could certain oils provide more nourishment and hydration than others, thereby altering my oiling schedule? What are the best practices recommended by hair care experts in this context?
