As fall settles in and winter approaches, dry, frizzy hair can make your blowouts look less polished than you’d like. However, Kyle Richards has a solution, and it doesn’t require a triple-digit trip to the salon. The Real Housewives of Beverly Hills star is a fan of the BioSilk Silk Therapy Original Leave-In Hair Treatment, which she says makes her hair “feel like silk.” Even better, it’s on sale for just $22 on Amazon right now.

During a recent Amazon Live, Richards shared her love for the leave-in treatment, which is designed to smooth strands, add shine and improve the appearance of dry or damaged hair. She noted that she uses the standout product every time she washes her hair. “People ask me a lot, like, ‘Why is your hair so shiny?’ And that’s the only thing I can think of. I do try to take care of my hair, but the silk look like that comes from something like this.”

The treatment’s lightweight formula helps smooth the hair cuticle, tame flyaways and give dull strands a glossy shine. Unlike heavier styling products that can leave hair looking weighed down, this one delivers softness without making hair appear greasy.

For an extra-smooth blowout, just work a small amount through damp hair, then fire up the blow dryer. You can also apply a little to dry strands to help tame frizz and flyaways, or even give second-day hair a quick refresh.  And because you only need a small amount at a time, it’s the kind of product that can earn a permanent spot in your beauty routine.

Amazon shoppers seem to agree that the treatment seriously delivers.

“It brings back a soft feel and takes away the look of dry texture without leaving greasy-looking residue,” wrote one five-star reviewer. “It keeps it from breaking and allows me to brush it without tons of breakage.”

A little also goes a long way. “I put a tiny bit on in the morning when my hair is wet, and I blow it dry, and then when I’m finished I put a tiny bit more on through my hair, and it shines and stays in place and doesn’t get frizzy every single day,” wrote another five-star shopper. “It is my go-to product for my hair.”

If your hair could use a little extra shine and softness, Richards’ favorite leave-in treatment might be exactly what your self-care routine is missing. On sale right now for just $22 on Amazon, it’s a surefire way to give dry, dull strands some extra love without splurging on a pricey salon treatment.
