The looks can change. The skin routine underneath should not.
A nikah week usually runs manjha, mehndi, nikah, walima. Different colours, different jewellery, sometimes different artists. The one thing that must not change is what you put on your face at night.
Manjha — turmeric, usually at home, usually yellow clothes. Shade, no scrubbing after. Mehndi — long hours sitting. Eat before, drink water through it, and keep your hands still after so the colour takes. Nikah — often quieter and more covered. A light, well-set base works better here than a heavy one. Walima — the big evening. This is where the heavier look belongs.
A dupatta pinned over the head for hours flattens hair and can pull at the hairline. Ask for a hairstyle built to carry pins. And ask for the pinning to be done where the hair is strongest, not at the temples.
3 months before: The slow list. 6 weeks before: Last deep facial. 3 weeks before: Trial for the walima look. The nikah look can be lighter and simpler. 1 week before: Threading and waxing.
Same night routine through the whole week. Light base for the nikah, heavy for the walima. Pins away from the temples.
You can, but tell each one what the other is doing. Two artists who do not speak to each other is how a bride ends up with two entirely unrelated faces in one album.
A low, structured style, pinned with the dupatta in place, and pins set away from the temples where the hair is finest.
