Day shampoo, night shampoo: why your scalp deserves a routine too

By Seoulma · · 4 min read

You already switch from a light morning moisturizer to a richer night cream. Your scalp has the same kind of day and night needs, and Treecell builds a shampoo around each: Day Collagen Shampoo (Morning of Resort) and Night Collagen Shampoo (Midnight Forest).

Quick answer Choose Day if you shower in the morning and want volume and a fresh, floral finish. Choose Night if you shower in the evening and want a deep clean with a cooling, calming feel. Use both if you wash at different times.

Day Collagen Shampoo: Morning of Resort

Made for people who wash their hair in the daytime. It gently removes scalp greasiness, adds volume, and replenishes protein and moisture for dehydrated strands. Key ingredients include hydrolyzed collagen, caffeine and niacinamide, plus amino acids and seaweed extracts such as kelp and wakame. The scent is a fresh floral blend of rosemary, bergamot, neroli, jasmine and ylang ylang.

Best for: fine or flat hair that needs lift, and anyone who wants a fresh start to the day.

Night Collagen Shampoo: Midnight Forest

Made for evening showers. It cleanses the scalp of excess sebum, dirt and product residue at the end of the day while leaving it feeling moisturized and balanced. Centella asiatica, houttuynia cordata and menthol help soothe the scalp and add a cooling sensation, and the forest-inspired scent is calming.

Best for: an oily or tired scalp after a long day, and anyone who showers before bed.

Why switch?

1. It treats your scalp as skin

The formulas use familiar skincare ingredients such as niacinamide, salicylic acid, panthenol and centella. Salicylic acid exfoliates dead skin cells on the scalp, which can help with dryness and oil build-up.

2. One shampoo no longer has to do everything

Morning and evening washes do different jobs. Day is for volume and freshness, Night is for a thorough clean and calm. Pick the one that matches when you shower.

3. Collagen and amino acids

Both shampoos contain hydrolyzed collagen and are built around plant and marine extracts, not just cleansing agents, so hair tends to feel softer and more moisturized.

4. A nicer ritual

Two distinct scents, a cooling finish at night and bottles that look good on a shelf make washing your hair feel less like a chore.

How to switch

  1. Morning showerer: use Day.
  2. Evening showerer: use Night.
  3. Both: use Day on wash days when you want volume and Night when your scalp needs a reset.
  4. Massage into the scalp for a minute before rinsing, and give your hair two to three weeks to adjust.
