Your face is wide and soft, so everything here is about adding height and removing width. If you mess that up, your face just looks more circular
1: Straight Hair
Men: Quiff
Women: Long straight layered hair
Straight hair holds shape well, so for men the quiff adds vertical height which makes the face appear longer, and the shorter sides reduce width. For women, long straight layers pull the face downward visually, which counteracts roundness and makes it look slimmer
2a: Wavy Hair (Loose waves)
Men: Wavy top with taper
Women: Long waves below chin
Loose waves naturally add volume, so you keep that volume on top while tapering the sides to avoid width. for women.\ starting the waves below the chin avoids expanding the cheek area, which would make the face look wider
2b: Wavy Hair (Messy / textured waves)
Men: Messy wavy quiff
Women: Loose messy waves with length
The messiness adds height and irregularity, which breaks the circular shape. It works because the volume is vertical
2c: Wavy Hair (Controlled waves)
Men: Side-parted waves with lift
Women: Wavy high ponytail
Controlled waves let you direct volume upward instead of outward, while the high ponytail for women pulls everything vertically, elongating the face.
3a: Curly Hair (Loose curls)
Men: Curly top with fade
Women: Long layered curls
Curls naturally add volume, so the key is keeping that volume upward while removing it from the sides
3b: Curly Hair (Tight curls)
Men: Tapered tight curls
Women: Defined curls with volume control
Tight curls can turn into a sphere if unmanaged. Tapering and controlling the sides prevents width from controlling ur face
3c: Curly Hair (Forward curls)
Men: Curly fringe with height
Women: Curly updo
Forward curls can shorten the face if overdone, so you keep some height for men. For women, pulling curls upward into an updo creates vertical emphasis (again making it appear slimmer)
4a: Thick / Coarse Hair (Heavy density)
Men: Structured quiff
Women: Long layered thick hair
Thick hair is perfect for creating height, while layers for women prevent the hair from expanding sideways
4b: Thick / Coarse Hair (Controlled bulk)
Men: High volume top with tight sides
Women: Thick high ponytail
Keeping it on top balances the face, while removing it from the sides prevents widening.
4c: Thick / Coarse Hair (Natural volume)
Men: Pompadour
Women: Layered thick length
Natural volume can help you if directed upward
