Hair growth patterns
Hair growth patterns can affect the choice of styling technique. For cowlicks avoid fringes; instead, suggest a side half fringe the works with the cowlick.
For widow’s peaks avoid fringes completely and suggest styles that are styled with the top area going over to one side or straight back.
For double crowns suggest maintaining a little length around the crown area and ideally work the natural fall into the style.
For nape whorls suggest maintaining the length at the nape area, or at least a little weight. Avoid cutting into the hairline.
Head and face shape
The head and face shape can affect the choice of style. Always aim to achieve a style which makes the face look oval shaped.
For round face shapes, avoid styles that add more roundness, such as too much width. Try to suggest styles that come onto the face.
For oblong face shapes, avoid styles that come onto the face; encourage width, avoid height and suggest a fringe to shorten the illusion of a long shape.
For square face shapes, suggest softer styles that soften the jawline.

FACTORS TO CONSIDER BEFORE FINISHING HAIR
Hair type
Hair type can affect the choice of tools, products and equipment
Specialist products for curly hair maybe required. Using strong mousse or spray could give the hair a “crispy” feel
Straight hair might not achieve the desired result if a client requires body. So products, styling tools and even a body perm may need to be considered to achieve the result
Texture
Texture can affect the choice of tools, products and equipment
Coarse textured hair may not suit the desired look; you will need to recommend smoothing products to help achieve the result
Density
Density can affect the choice of tools, products and equipment
Abundant hair may require more product when styling to achieve the required look
Sparse hair should avoid heated oil based products as it could result in a greasy finish
