Sunday Product Usage – Frequently Asked Questions

Q1: What’s the difference between Sunday Shampoo and Day Day Shampoo? How should I use them together?


A: Sunday Shampoo is designed for deep cleansing once a week, helping remove buildup and residue from the scalp and follicles.

Day Day Shampoo is for daily gentle cleansing, maintaining scalp balance and freshness.

Recommended use: Day Day daily, Sunday once a week for a complete scalp routine.


Q2: My hair feels drier after washing—does that mean the product is too harsh?


A: Not at all. Sunday products are free of silicones and heavy coating agents, so what you feel is your hair in its natural, clean state.

If you’re used to ultra-smooth shampoos, you may notice a temporary roughness as your hair detoxes from buildup. Use with our hair mask or oil during the transition—your hair will rebalance in 1–2 weeks.


Q3: Can I use the Scalp Relief Essence on wet or dry hair?


A: Both! This leave-in essence is suitable for wet or dry application. We recommend applying after shampooing while the scalp is still warm and absorbent. For itchiness or redness, apply anytime during the day for relief.


Q4: How long should I leave the Magic Hair Mask on? Can I use it every day?


A: Leave it on for 1–2 minutes, or up to 5 minutes for very dry hair.

We suggest using it 2 times a week, or more frequently if your hair is damaged, bleached, or frequently heat-styled.


Q5: Is the Sheen Hair Oil for styling or treatment? Will it feel greasy?


A: It’s made for both! This lightweight, non-greasy oil helps protect against heat, add shine, and smooth dry ends.

Apply a few drops before blow-drying or as a final step after styling—just a little goes a long way.


Q6: Do I really need to use the Glowing Brush daily? How many strokes are enough?


A: We recommend brushing once or twice a day, about 50–100 strokes each time, from roots to ends.

This boosts scalp circulation, helps distribute natural oils, and supports long-term scalp and hair health.


Q7: Is Sunday safe for sensitive skin, pregnancy, or children?


A: Yes—Sunday products are free from sulfates, silicones, and harsh preservatives.

Our Day Day Shampoo and Scalp Relief Essence are especially gentle and have been tested for sensitive skin. For medical concerns, we always recommend checking with your doctor first.
