Hair & Skin Care Guide

What the Hash Spa team tells every client after a session — practical tips that make your service last longer and save you extra visits.

After keratin or protein treatments

• Don't wash your hair for 72 hours, and avoid tying it or tucking it behind your ear.
• Use a sulfate- and salt-free shampoo — regular shampoo cuts the result's life in half.
• Limit heat styling and always use a heat protectant when you do.

After colour or balayage

• First wash after at least 48 hours, with lukewarm water rather than hot.
• A nourishing mask weekly, plus a protein mask every three weeks for lightened hair.
• Refresh roots every 6–8 weeks and toner every 4 weeks to hold the shade.

After facial sessions

• Avoid direct sun for 24 hours and wear SPF 50 daily.
• No exfoliants or retinol for three days after the session.
• Best results show after 3–4 sessions spaced two weeks apart.

Before a big occasion

• Book your facial a week before the event, not the day before.
• Schedule a bridal makeup trial at least two weeks ahead.
• Arrive 10 minutes early — appointments start exactly on time.
