What is the most important factor when selecting hair products for clients?

Selecting hair products tailored to a client's individual hair type and needs is essential because each person's hair has unique characteristics, such as texture, porosity, density, and scalp condition. By understanding these factors, a cosmetology professional can recommend products that will effectively address specific concerns—like dryness, oiliness, color retention, or curl definition—leading to better results and increased client satisfaction.

Using the right products ensures that clients receive the best possible care and support for their hair goals, promoting healthy hair practices and potentially preventing damage. While factors like brand name, cost, and availability might influence product choice, they should not overshadow the necessity of matching the product to the client's unique hair qualities for optimal effectiveness.
