What do these products do?

Triple-action Boldify Hair Boost Serum is an all-in-one volumizer, leave-in conditioner and thermal protectant that provides instant fullness and deeply nourishes strands. Over time, this Biotin-infused formula promotes scalp health, helping to maximize hair growth and reduce fall and breakage for longer, stronger locks!

Our Hair Thickening Spray helps to give hair volume, fullness, and texture for hold. When applied during styling, the result is immediate, and lasts until the next wash (touch-ups may be required if you go multiple days between shampoos).  

What are the instructions for use?

Serum: Wash/condition hair as usual, towel dry. Squeeze a small amount (a dime-sized amount for short/mid-length hair, a nickel-sized amount for longer hair) into your palm, and rub hands together before applying evenly, starting at the ends and working your way towards the roots & scalp. Blow-dry for optimal volume, or air-dry for natural fullness. 

Thickening Spray: Wash/condition/rinse hair, then air or blow-dry until hair is only slightly damp. Apply the Thickening Spray lightly and evenly, from root to tip, being sure not to over-apply (as this can cause stiffness/undesirable texture). If blow-drying: Use a round brush for lift at roots and 3 times the volume. If air-drying: Tousle lightly with fingers throughout for natural fullness. Style as usual.

Does Boldify contain Minoxidil, Rogaine, or other hair re-growth agent(s)?


Boldify products are all-natural styling products intended to promote a healthy scalp and stronger strands; they are not and do not contain drugs or supplements, and are not intended to treat medically-induced or genetic hair loss like Rogaine and similar products. 

Most hair growth products require multiple applications per that true of Boldify Hair Boost Serum?

Boldify Hair Boost Serum is a styling agent that supports a healthier scalp and fuller, longer, stronger hair naturally by providing nourishment and protection to the strands, and being residue and buildup free to keep the scalp cleaner and maximize follicular function for faster growth over time.

Do you rinse the Serum out, or leave it in?

This Serum is a leave-in conditioner, thickener and thermal protectant.

Do these products contain phthalates, parabens or sulfates?

No. Boldify Hair Boost Serum and Hair Thickening Spray are FREE of phthalates, parabens and sulfates.

Are the Serum and Thickening Spray gluten free?

Yes, both products are indeed gluten free.

Are these products cruelty free?

YES! All Boldify products are created and manufactured proudly via cruelty-free methods and processes.

What do the products smell like?

Boldify Hair Boost Serum has a light, fruity smell, while the Thickening Spray has a light, fresh scent - both of which dissipate post-application. 

Is the Thickening Spray a pump or an aerosol?

Boldify Hair Thickening Spray is applied with a non-aerosol pump spray nozzle (included).

Is the Serum a spray, or is it applied with your hands?

Boldify Hair Boost Serum is a lightly-textured liquid that is applied with the hands.

Is this okay to use if I’m air-drying my hair, or do I have to blowdry?

Both products can be used for air OR blow-drying. 

Air-drying hair after applying Boldify Hair Boost Serum will provide a natural fullness and promote scalp health over time; blow-drying will provide optimal volume, while the thermal protectant works to halt damage commonly associated with heated styling methods.

Air-drying after applying our Hair Thickening Spray will provide even more fullness and a light texture/hold, while blow-drying will maximize the benefit for 3X more volume! 

Will this work on dry hair?

Boldify Hair Boost Serum is intended for use on freshly-washed, towel-dried hair; we do not recommend applying to dry hair. 

Our Hair Thickening Spray is intended for application on slightly damp hair; we don’t recommend applying to fully dry hair. For between-wash touch-ups, you can lightly spray with water to dampen hair, then apply the Thickening Spray, lightly and evenly, from root to tip before styling as usual.

Is this bundle suitable for all hair colors and types?

Absolutely! Boldify Serum and Thickening Spray are colorless, and provide benefits for all hair types and textures!

Will this take the curl out of my naturally curly hair, or define it?

Boldify can absolutely be used on naturally curly hair. For best results, we recommend applying the Serum to freshly washed, towel-dried hair, then scrunching/finger-spiraling curls before allowing hair to air dry. For added volume/texture/hold, apply the Hair Thickening Spray evenly and thoroughly to barely damp hair just before it finishes drying, scrunching curls lightly once again to maximum effect.

Can I curl/flatiron my hair still?

Absolutely! After the products have been applied per their individual instructions, brush/comb through and finish drying as desired; then, simply curl or flatiron as you normally would. The Serum offers stellar thermal protection from the harsh heat of such styling tools, and the Thickening Spray offers up added texture for enhanced hold! 

Are these products safe for use with hair extensions?

While we certainly have customers that successfully use Boldify with their extensions, we always recommend consulting your Stylist for advice beforehand.

Is this safe for use on keratin-treated hair?

Generally, yes. However, we recommend checking with your stylist before using if your hair is chemically processed.

Will this work for short hair?

Yes. Boldify products are great for all hair lengths!

How big are these bottles?

Each bottle contains 4oz of product.

Will this leave hair looking shiny?

Serum: The finish the product provides is largely dependent upon your styling method, and the products with which it's combined; in general, the Serum softens and smooths locks, and helps to prevent fly-aways. 

Thickening Spray: This spray provides enhanced texture for styling hold, resulting in a light matte finish. 

Does the Thickening Spray make hair brittle or feel "crunchy"?

When applied lightly and evenly, no; however, over-saturation can weigh hair down and cause an unintended change in texture.

Does Boldify make hair greasy?

Not when applied as instructed; however, over-application - or application to overly wet or fully dry hair - can weigh strands down and cause an unintended change in texture. 

Does it make hair feel sticky?

Not when applied as instructed - however, over-application of the product can negatively affect texture.

Is the Thickening Spray easy to wash out?

Yes! Boldify products wash out cleanly and easily in a single shampoo.

Can these products be used in conjunction with other Boldify products?

Absolutely! We recommend adding products to your routine 1 at a time, as each combination will heed a unique result for each individual.

Do I have to use both the Serum and the Thickening Spray?

No! Each product offers its own unique benefits, and can certainly be combined - or NOT combined - with eachother (or other Boldify products) as you see fit.

Some days, the softness that the Serum provides may be just what you're looking for, while other days the Thickening Spray provides the textured, beachy finish you're craving! 

Are these products safe for use on children?


As with any product, we recommend reviewing the ingredients for possible interactions if the user has allergies/sensitivities. 

Always avoid contact with eyes; do not ingest.

Can I use these on my beard?

As long as the product isn’t ingested, application to facial hair is generally safe. 

However, the contained Biotin in our Hair Boost Serum may not be ideal for facial skin, and you may find that the texturizing effect of the Thickening Spray isn’t ideal for facial hair.

What if I buy it, and end up not liking it?

We stand fully behind all Boldify products with our Satisfaction Guarantee. If you purchase any Boldify product and are not completely satisfied, simply send us an email here and let us know; we’ll issue a full refund of the purchase price within 1 Business Day!
