Haircare experts and specialists have provided guidance on the effective use of products and common maintenance mistakes.

Initial advice focused on the function of hair oils and masks, noting that oils can seal the hair cuticle to reduce breakage and frizz. Experts distinguished between leave-in and rinse-out masks and warned that while silicone-infused oils protect against heat, they can cause buildup. 

Subsequent guidance expanded to include proper shampooing techniques, such as applying product to the scalp rather than hair lengths, and the importance of using heat protectants. Additionally, professionals addressed the use of rosemary oil, cautioning that it must be diluted with a carrier oil to prevent scalp irritation.
