Hair dryers, straighteners, shavers, trimmers and grooming from Wahl, Philips and Black & Decker.
For hair tools, the heat setting range matters more than the wattage. Fine or coloured hair needs a lower setting than a single-temperature dryer provides, and ceramic or tourmaline plates distribute heat more evenly than bare metal.
For shavers, the real choice is foil versus rotary. Foil suits straight, fine hair and daily shaving; rotary handles coarser growth and works better on a neckline. Both need the head replaced roughly once a year — a shaver that has stopped performing usually needs a new head, not a new shaver.
Wahl clippers are the professional standard and worth it if you cut hair at home regularly.
