Worked Explanation: Before using any new chemical product, particularly an unfamiliar brand, reviewing the Safety Data Sheet (SDS) is paramount. The SDS provides essential information on safe handling, storage, required personal protective equipment (PPE), first aid measures, and emergency procedures. This ensures the stylist is fully informed about potential hazards and how to mitigate them, protecting both themselves and clients. While patch testing (D) and strand testing (A) are critical for client safety and service outcome, and proper storage (B) is important, understanding the chemical's inherent risks via the SDS is the foundational safety step for all new products.

Worked Explanation: An oblong face shape benefits from styles that add horizontal width and reduce vertical length. A chin-length bob adds width at the jawline, while a full blunt fringe shortens the appearance of the forehead, effectively reducing the overall perceived length of the face. Adding volume at the sides further enhances width. Vertical layers (A) and sleek, long styles (D) would further elongate the face. A pixie (C) might work depending on side volume, but minimal volume on top and close-cut sides might still emphasize length.

Worked Explanation: This is a critical contraindication. 'Black henna' tattoos often contain high concentrations of paraphenylenediamine (PPD), a common ingredient in permanent hair dyes. A severe reaction to 'black henna' is a strong indicator of PPD allergy, and applying a permanent hair colour containing PPD would almost certainly trigger an even more severe, potentially life-threatening, allergic reaction. This client should be strongly advised against using any PPD-containing hair colour and offered alternatives like vegetable dyes or temporary colours without PPD.
