Your fail-proof remedy for lackluster, straw-like locks? Lots of colorful knit caps.

Now that hat-head days are numbered, prep your mane for the big reveal with Salon Tenshi’s intensive scalp treatment.

The process, which soothes dry, itchy skin and removes gunky buildup, begins with a tingly, eucalyptus-infused oil rubbed onto the roots followed by an ultra-conditioning mixture of jojoba and egg yolk to add protein and strengthen strands.

Zone out under a high-tech contraption that emits colored light (red to increase circulation and promote hair growth, blue to calm irritated skin). One shampoo and a vigorous massage later, every last flake is banished.

Ask about the optional steam treatment to seal in moisture and recommended products to supplement your at-home regimen.

You could use a few purls of wisdom.

Available at Salon Tenshi, 537 North Tenth Street (215-232-8090 or salontenshi.com), $30-$60.
