Avoiding harsh chemicals in skincare and haircare products is crucial for maintaining the health and integrity of the skin and hair between treatments. Clients at SOS Wax and Skincare should be advised to choose products that are free from sulfates, parabens, and synthetic fragrances, which can strip the skin and hair of their natural oils and cause irritation. Recommending gentle, natural products that are designed to nourish and protect helps clients maintain their treatment results and support long-term health. This tip is especially important for clients with sensitive skin or those who receive regular chemical treatments, as avoiding harsh ingredients helps prevent irritation and promotes overall skin and hair wellness. Providing this advice ensures that clients can care for their skin and hair with products that complement their in-spa treatments, leading to better results and greater satisfaction.
