About this item

  • WEIGHTLESS CONDITIONING: BOLDIFY Nourishing Leave-In Serum is designed to deliver serious care without weighing hair down. Infused with powerhouse ingredients like our BOLD Complex, Aloe Vera Leaf Juice and Niacinamide, this BOLDIFY Serum outperforms even the best hair thickening products on the market by serving the cause rather than the symptoms over time, making it the perfect hair thickener for both men and women with fine hair.
  • GET THE LOOK, NIX THE DAMAGE: This BOLDIFY professional hair care product is also a thermal protectant, safeguarding your precious locks from heated styling tools up to 450F so that you can blow dry, straighten and curl your way to a fuller finish without worrying about damage in the long run. It's an essential biotin oil alternative hair serum heat protectant that every hair care routine needs!
  • FEWER TANGLES = STRONGER, LONGER STRANDS: Our Serum is more effective than other detangler spray products, providing the necessary nourishment to banish tangles instantly. Fewer tangles equals less damage and breakage; less damage and breakage means stronger strands over time -- and we all know that stronger hair grows longer! Enriched with Aloe Vera and Biotin, this Serum hydrates better than other biotin hair growth serums that men and women like you have settled for in the past.
  • SOFTER, SMOOTHER, SHINIER FINISH - EFFORTLESSLY: BOLDIFY anti-frizz hair treatment serum offers superior frizz control for those with thinning hair without the oily appearance and greasy finish of other split ends and hair protector treatments. Enjoy a softer, smoother, shinier finish with every bit of the volume your styling routine can acheive!
  • MULTI-PRODUCT FUNCTIONALITY IN ONE BOTTLE: Ditch the multi-product haircare routine for a simplified, single-step Serum. Biotin hair masks, hair shine serums, treatment sprays, detanglers, and thermal protectants are all wonderful and necessary -- but that doesn't mean they have to be separate! Get all the benefits in just one bottle with BOLDIFY Nourishing Leave-In Serum.

Product Description

Nourishing Leave-in Serum

SKINCARE FOR YOUR HAIR

Our Nourishing Leave-in Serum is a multitasking formula that delivers serious care without weighing hair down. Infused with our bold proprietary blend and aloe vera, this serum provides essential nutrients and hydration to condition, detangle, soften and protect hair from heat (up to 450°F).

Nourishing Leave-in Serum
SULFATE-FREE

NO "IFFY" INGREDIENTS

Stylist-formulated for salon-quality product. Color-safe, cruelty-free, SLS/SLES, paraben, and phthalate free. We left the "iffy" ingredients out so you can feel confident using our Nourishing Leave-in Serum.

Leave-In Serum
NOURISHED AND READY FOR STYLING

FULLER & HEALTHIER-LOOKING HAIR

Our formula put the care in haircare. This lightweight, leave-in melts into hair leaving no greasy or heavy residue that works on all hair and scalp types and routines. Hair is left looking and feeling healthier, nourished, and ready for styling.

Leave-in Serum Ingredients
INFUSED WITH HAIR-LOVING INGREDIENTS

DELIVERING MUCH NEEDED NUTRIENTS TO STRANDS

A blend of aloe vera leaf juice and niacinamide provides hydration, softness, and antioxidants. Our BOLD COMPLEX contains a proprietary blend of well-researched hair loving ingredients to deliver healthier, fuller, and more voluminous looking and feeling hair with every wash and style.

What are the ingredients?

Please see the “Important Information” section within the Product Listing for this information.

Will this Serum make my hair greasy?

No! Our Nourishing Leave-in Serum is specifically formulated for fine and thin hair, which means all the benefits of a quality styling Serum - detangling, plumping, smoothing - with none of the weight.

How heavy a scent does this product have?

Our Nourishing Leave-in Serum has a light and refreshing scent with notes of bergamot, sage, jasmine, apple, and honeydew for an aromatic experience during styling without a heavy, overwhelming scent.

Is this the same as a leave-in conditioner?

While the detangling and smoothing capabilities of our Serum make it similar to a leave-in conditioner, its weightlessness and plumping effects set it apart as a truly unique, multi-functional styling agent!

Can this be used alongside other BOLDIFY Products, like the Thickening Spray and Root Boosting Spray?

Absolutely! Any and all BOLDIFY products can be used together - it’s just about finding the right combination for your locks! Be sure to apply products in the correct order according to their individual instructions for maximum volume.

At long last something that really works for volume!
5 Stars
At long last something that really works for volume!
At long, long, last I have found something that truly gives volume to my thinning hair. I used this product once, and will never use anything else. I wish I had taken before photos, but I did not expect such amazing results! The front top of my hair is thinning so much from thyroid disease I was ready to buy a hair piece to cover it up, but I can put that off for now.After using this product ONCE applied only on the top for volume, the results are truly amazing. I have volume, and the thinning is less noticeable. The first photo shows how far back the thinning goes, almost 2 inches. The second photo is of the top of my head after I combed my hair as usual.Can't comment on if it helps hair growth since I only used it once, but I very, very, highly recommend for its superior hair thickening properties.
