Holi is one of the few Indian festivals with no gifting convention attached to it, which is either a problem or a licence depending on how you look at it. There is no expected item, no equivalent of the Diwali sweets box. That means a father won't be measuring what you give against anything — but it also means a generic hamper lands as filler. The useful angle is the aftermath: what does the day actually do to him, and what makes the recovery easier.
Under ₹1,000 is the right ceiling here precisely because Holi isn't a milestone. Spend more and you make the occasion carry weight it doesn't have, and he'll ask why. The range on this page — ₹298 to ₹799 — buys grooming hardware, a steel analog watch, a replacement wallet, headphones. Practical, unceremonious, used within the week.
Two warnings specific to the day. First, don't gift anything electronic that he'll be tempted to take outside while the colour is still flying; none of the audio picks here state a water or dust rating, so they are for the evening and after, not the afternoon. Second, if you're choosing between the two trimmers, the Bombay Shaving Company one has six comb lengths down to 1mm for taking a beard right back, while the Vega listing states a two-year warranty. Both rinse clean, which is the part that matters on this particular festival.
