The second group is about the blow dry, and this is where IGK's salon roots show most. The names are a running joke, all Good Behavior, Antisocial and so on, but the job is serious: prepare hair before heat, then finish it so it looks smooth.

The Good Behavior 4-in-1 Heat Protection Blow Dry Prep Spray is the first thing on damp hair, before any dryer touches it. The Smoothing Heat Protectant Blowout Balm is the balm option if you prefer that to a spray. I like the Spirulina Protein Anti-Frizz Smoothing Spray as a finishing mist, because it is light enough not to flatten a blowout. The Frizz and Flyaway Lightweight Gel Hair Taming Wand is a bit like a mascara for the flyaways around the hairline and the crown, and it is the easiest thing here to toss in a bag.

Then the masks. The Antisocial Bond-Building Repair Dry Hair Mask goes onto dry hair, so it feels like a treatment with little fuss. The Antisocial Leave-In Dry Hair Mask stays in too, which makes it a good pick when a rinse-out step just will not happen. For both, start with a small amount at the ends and add only if hair still feels rough.

A quick test: if a blowout feels stiff by the afternoon, you used too much, not too little. Comb the prep spray through from roots to ends while the hair is still damp, so every section gets the same amount, and let the masks sit as the label says.

Wash day is the quiet part of the routine, and the Pay Day Instant Repair Shampoo and Pay Day Instant Repair Conditioner are a pair built for it. Use them together and think of them as the base that everything else sits on. The MISTRESS Hydrating Leave-In Conditioner Hair Balm is the extra layer after the shower, a soft balm for ends that feel dry and tangled.

The color side of the shelf is where I have the most fun. The Color Depositing Gloss Mask is a tinted mask that adds a wash of shade while it conditions, so it suits anyone whose color looks tired between salon visits. The Hi-Shine Gloss Treatment is the finishing step, the one I would use before a dinner or photos, when hair should catch the light. Comb gloss through so that it goes on evenly.

What I would skip: layering a rich balm, a mask and a gloss all in one wash. Hair goes flat and heavy, and you will blame the products. Pick one extra step for the day, and keep the rest of the shelf for another wash, use a tinted mask on a clean towel and old gloves, and test a small section first if your color is very light.

If your scalp is itchy or sore after using anything, stop and ask a doctor or colorist.

If I had to build a routine from all of this, it would be short. Shampoo and conditioner on wash day, a prep spray before heat, and one texture product for day two. Everything else is an occasional extra, and none of it is required every week. Start with the two steps your hair complains about most, live with them for a month, then decide whether the shelf needs more.

Choose by what your hair does at four in the afternoon. If it goes flat, the texture spray or foam helps. If it frizzes, the smoothing spray and the taming wand are the quick fixes. If the color looks dull, reach for the gloss mask.

IGK feels like salon advice in a bottle, so treat it that way: ask what your stylist would do and do that. One step, done well, beats five done in a hurry.
