The Ultimate Mother’s Day Gift Guide: 35+ Perfect Picks for Every Mom (and Budget!)

My mom recently told me that she felt my hair looked a little “flat.”

(OK Mom—tell me what you really think!).

To be fair, she wasn’t wrong. I haven’t been spending much time styling my hair, and that’s noticeable now that I’m in my 30s. Even within the past two years, my hair has felt … different. I can’t quite put my finger on it. Maybe it’s thinner? Duller? Either way, it just doesn’t grow like it used to.

I blame collagen loss. Collagen is a structural protein that strengthens and repairs hair follicles, supporting scalp health, and promoting hair growth. The sad news is that collagen production decreases beginning in your mid-20s. Cue me chatting with the experts to uncover which hair products will actually boost collagen, stimulate hair growth, and bring back that youthful luster!

Sports Research Collagen Peptides for Women & Men ($29.65)

Sourced from grass-fed, pasture-raised bovine, experts say that this high-quality hydrolyzed collagen powder supports healthy hair growth, strength, and shine from within. One user on Amazon noted that after taking this every day, “people I know are saying that my hair is growing so fast! I certainly have to agree!”

To use, mix one scoop of collagen powder daily into your preferred drink. It tastes great in smoothies and coffee, and dissolves in water.

Nutrafol Women Hair Growth Supplement ($83.60)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (3)

Everything I’ve read about Nutrafol tells me it’s especially great for women experiencing post-partum or age-related hair thinning. The dermatologist-recommended supplement provides collagen support to target the key causes of thinning hair (i.e. hormone shifts, aging, and metabolism). Expect visibly thicker, fuller, and stronger hair within weeks.

Vegamour GRO Hair Serum ($64)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (4)

Formulated with strengthening peptides and plant-based phytoactives like Red Clover and Mung Bean, this viral hair serum is a gamechanger. It works to reduce hair shedding and fallout, as well as increase the appearance of hair density. Users note that while the product is a little bit “runny,” it sinks into the scalp for a hydrating feel (and doesn’t ever look greasy).

P.S. I can’t get over how pretty this bottle is.

Drunk Elephant Silkamino Mega-Moisturizing Shampoo ($27)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (5)

Silk amino acids and hydrolyzed proteins combine to strengthen brittle, color-treated, or damaged hair. This mega-moisturizing shampoo also includes Virgin Marula Oil, a fatty acid that will restore shine as it strengthens and softens. After using the product, one person said, “My hair is stronger, less shedding, and shinier!”

Drunk Elephant Silkamino Mega-Moisturizing Masker ($30)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (6)

Just like its name suggests, Drunk Elephant’s “Silkamino” mask is infused with hydrolyzed silk, silk amino acids, and silk sericin for soft, ultra-moisturized hair. Experts love how it mimics collagen and reinforces the strength of each individual hair strand. It’s perfect for extra-thirsty/damaged hair!

Briogeo Don’t Despair, Repair! Deep Conditioning Mask ($39)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (7)

The brand’s best-selling 15x award-winning Deep Conditioning Mask for a reason, it strengthens and repairs dry, damaged hair. Experts say that this cult-favorite mask is loaded with collagen-supporting ingredients like Vitamin B, Rosehip Oil, and Algae Extract. In other words, it’ll help infuse your hair with noticeable strength and bounce.

OLLY Undeniable Beauty Gummies ($11.36)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (8)

Olly Undeniable Beauty gummy vitamins promote hair health with ingredients like biotin, Vitamin C, Vitamin E, and Keratin—all of which support natural collagen production. And apparently, the naturally-flavored gummies even taste good!

Pro tip: Stack these gummies with collagen powder for double the health benefits.

Kérastase Densifique Hair Density Serum ($62)

Experts Weigh In On The Best Collagen-Boosting Hair Products That Help With Growth, Thickness, And Shine (9)

Disclaimer: I’d trust anything that came in a Kérastase-branded bottle. And the brand’s Densifique line (including this luxurious serum) promises to increase the density of your hair by cutting down on breakage and shedding. This product strengthens the hair shaft, supporting follicle function and hair anchoring to bring back bounce and body. Hooray!
