Real Housewives of Beverly Hills star Kyle Richards swears by this hair elixir which she explains gives her mane “the look and feel of 3,000 extra strands.”

The lightweight, non-sticky spray is made with keratin, collagen and biotin and – according to both Richards and numerous five-star reviewers – effectively increases hair volume and strengthens fine and thin hair. “I’ve tried three other spray-in hair thickeners and this is the only one that really made my hair fuller,” said one five-star fan. “The price is also reasonable. I can’t afford super expensive hair products that I use every day.”

Boldify’s Hairline Powder is not only one of our best gray root touch-up products of the year, it’s also great for filling in a thin hairline. If you have silver roots and suffer from thinning hair, this might be your ticket. It’s not as harsh as some spray formulations and it washes out easily – all of which is crucial for maintaining fine, thinning hair and helping prevent extra shedding.

The color range here is impressive: there are 14 to choose from, including three blonde. There’s even a silver option, if you’re interested in keeping your gray tones while filling in the spots and making your style look more robust. Final surprise bonus: the powder works a bit like a dry shampoo to absorb excess oil so you don’t have to shampoo as much.

With more than 26,000 five-star reviews, this plant-based formula – containing olive, coconut and jojoba oils – works to promote hair growth and strength safely and naturally. The blend of oils is the magic formula here: Coconut oil helps hydrate hair and repair split ends (same with jojoba oil), keeping new hair growth hydrated and healthy; There is also some evidence that using olive oil on hair helps stimulate growth, including by strengthening hair follicles. And pumpkin seed oil isn’t just for fall recipes, folks: One study found the ingredient to promote hair growth in test subjects.

The oil not only encourages hair to grow longer and stronger, but also works to soften and detangle hair and reduce blow-drying time, which also helps reduce the amount of heat damage to strands during the styling process. All that for the current retail price of $9 really makes this a great bargain.

If you’re looking for a more concentrated oil to strengthen and thicken your locks, this rosemary potion from Kitsch might be for you. Topically applied rosemary oil is clinically proven to initiate new hair growth while preventing further loss. In fact, a 2015 study found that rosemary essential oil was as effective as minoxidil at growing new hair in mice.

This is an excellent rosemary oil if you want to try it out: Kitsch’s formula contains follicle-stimulating biotin and is also color-safe and safe for sensitive skin.

A major problem with fine, thin hair is that it’s difficult to find moisturizing, de-frizzing products that won’t keep your locks looking limp. Introducing OGX’s Weightless Dry Oil Spray, which helps smooth flyaways, repair split ends, and eliminate frizzy, frizzy summer hair without making it look greasy or heavy.

“This oil is extremely lightweight, doesn’t weigh hair down, and the spray bottle projects the perfect amount in each spray,” said one reviewer. “I have fine hair and it becomes soft and not greasy, and there is no lack of volume…”

At first glance, you might think, why on earth would I need a silk pillowcase? AM I AN EMPRESS? Are we in Hollywood in 1934? Should I go to sleep with a face full of cold cream and call people? Yes-ling? Do I also need a silk dressing gown and high-heeled slippers?

But then you learn the facts: Silk pillowcases support the health of both your skin and your hair. Research shows they can help prevent shedding and breakage and keep your hair from frizzing overnight, leading to less styling and an overall healthier mane.

There’s so much to love about this thickening, hydrating, salon-quality shampoo and conditioner duo. For starters, it contains no harsh chemicals. It is safe for all hair types (including colored hair) and not tested on animals. But the ingredients are the real stars here: Biotin, B vitamins and caffeine are proven to nourish fine hair follicles and help stimulate growth.

With 11,000 five-star reviews, this popular set is a bargain at 20% off. “My hair has never felt better,” said one reviewer. “My hair is thin, but it is not heavy. I also notice much less hair loss in my brush and styling tools.”

Some types of hair loss can be caused by product build-up on the scalp, and if your hair is both falling out and looking dull, Neutrogena’s Healthy Scalp shampoo can provide relief. It’s non-medicated, color-safe, and sulfate-free, and while the formula is strong enough to dissolve gunk build-up on your scalp and strands, it’s not too harsh to use occasionally on fine or thinning hair.

Best of all is the grapefruit scent, which is citrusy and fresh, but not sweet at all.
