As a Beauty Pro for women of color, it's important to understand the diverse hair types and textures of your clients in order to build a natural hair care regimen that works for them. Natural hair care is all about nourishing and moisturizing the hair from the roots to the ends. Here are some tips on how to build a natural hair care regimen for your clients.

1. Assess your client's hair type and texture Before you can build a natural hair care regimen for your client, you need to assess their hair type and texture. This will help you determine which products and techniques will work best for their hair. Take note of their curl pattern, hair density, and porosity level.

2. Recommend a gentle cleanser: A gentle cleanser is essential in any natural hair care regimen. It helps remove buildup and dirt from the scalp and hair without stripping away natural oils. Look for a sulfate-free shampoo or co-wash that's gentle enough for daily use.

3. Use a deep conditioner regularly: Deep conditioning is a crucial step in any natural hair care regimen. It helps restore moisture and nourish the hair from the inside out. Depending on your client's hair type and texture, you can recommend they use a deep conditioner once a week or every other week.

4. Leave plant based products: The key to hair growth and avoiding drying out natural hair is to use plant based and alcohol free products from the EVT   product line.

5. Suggest a moisturizing styling product: A moisturizing styling product helps lock in moisture and define curls. Depending on your client's hair type and texture, you can recommend a styling foam, O gel, or oil to help keep their hair moisturized and styled.

6. Advise on protective styling: Protective styling is an important part of any natural hair care regimen. It helps protect the hair from damage and breakage while promoting hair growth. Suggest protective styles like braids, twists, or buns that can be worn during colder and warmer seasons to avoid hair breakage. 

In conclusion, building a natural hair care regimen for your clients requires knowledge of their hair type and texture, and the use of products and techniques that are specifically formulated for their hair. With the right regimen, your clients can achieve healthy, beautiful, and manageable natural hair.
