Trends in night time beauty have seen the viral ‘slugging’ routine move from skin care to hair care, a technique that uses oil to lock in moisture overnight.

But hair care brands are now backing another bedtime trend: overnight scalp serums.

Of course, overnight treatments are a time-tested method for treating hair.

Hair oils have been used as a night-time treatment for centuries to provide a conditioning benefit and also help to reduce damage from friction during sleeping, long before it was repackaged as ‘hair slugging’.

However, while oils sometimes need to be washed off in the morning to avoid strands from feeling greasy and limp, and prevent product build-up, Aveda’s Principal Scientist Alison Pawlus, PhD, says that this isn’t an issue with serums.

“Overnight serums for hair have an upper hand because they are lightweight formulas with new technologies and powerful actives, as in our case with Botanical Repair Strengthening Overnight Serum.

This serum has a carefully formulated blend of naturally derived ingredients with hair strengthening and damage repair benefits.”
