Scalp and Hair Analysis Flashcards

What is the significance of hair colour level in scalp and hair analysis?

Answer: It helps predict how the hair will respond to lightening and reveals the contributing pigment that must be managed

Identifying the hair's natural level is crucial because it predicts which contributing pigments will be exposed during lightening, how much lift is needed, and helps formulate the correct colour product and developer strength.

What is a whorl in hair growth patterns?

Answer: A circular pattern where hair grows in a rotating direction around a central point, typically at the crown

A whorl is a circular growth pattern where hair radiates outward from a central pivot point in a rotating direction. Most people have one or two whorls at the crown. They affect how hair falls and must be considered when cutting.

What is the role of sebum in scalp health?

Answer: Sebum is a natural oil that lubricates and protects the hair and scalp, maintaining moisture and the acid mantle

Sebum is the natural oil produced by the sebaceous glands. It lubricates the hair and scalp, helps maintain moisture, contributes to the acid mantle's protective barrier, and gives hair its natural shine. Both excess and deficiency cause issues.

What condition might a stylist suspect if a client presents with yellow, crusted patches on the scalp and significant itching?

Answer: Seborrheic dermatitis or severe dandruff

Yellow, crusty patches with significant itching are characteristic of seborrheic dermatitis or severe oily dandruff. The yellowish colour comes from the combination of sebum and skin cells, and the condition often requires medicated treatment.

What should a stylist do if they discover nits (lice eggs) in a client's hair during analysis?

Answer: Immediately stop, inform the client professionally, and refer them for treatment — do not perform any service

Head lice (pediculosis capitis) is highly contagious and is a strict contraindication. The stylist must stop, inform the client discreetly and professionally, recommend they seek treatment, and sanitize all tools and surfaces. No salon service should be performed.

What is the importance of documenting all findings from a hair and scalp analysis?

Answer: It creates a baseline record for tracking changes, ensuring service safety, and maintaining consistency across appointments

Documenting analysis findings creates a baseline that allows tracking of changes over time, ensures appropriate service modifications, provides legal protection, and maintains consistency between stylists or across multiple appointments.
