Packed with 100% cruelty-free, natural ingredients, Boldify offers a wide array of hair thickeners that work instantly to deliver fuller, healthier locks. In this section, we cover 7 must-have Boldify products that can revive your lifeless, flat hair long-term.

Let’s face the truth: Straight, fine hair often tends to look a bit limp at times. It is time to try Boldify Hair Thickening Spray to instantly boost your entire head of hair without added weight, making it appear fuller and thicker. Boldify delivers a mild mist when you spray it without giving too much of an overpowering flowery scent.
Boldify has a lightweight formula and won’t leave a sticky build-up as mousse can. Instead, Boldify Hair Thickening Spray gives your thin hair plenty of body and doesn’t make your hair stiff and appear oily.
The only drawback users touted is that it is too pricey compared to others. Moreover, overuse of this Boldify spray may leave a tacky, residue feeling on your hair.
Hair Thickening Shampoo & Conditioner Duo

When you see a shampoo that claims to deliver thicker, fuller, more voluminous hair from the first wash, it’s hard to dodge especially if you have fine hair.
Packed with natural ingredients and vitamins, Boldify Hair Thickening Shampoo is perfectly paired with Hair Thickening Conditioner to fortify and strengthen your hair while also providing an effortlessly bouncy volume to flat or limp hair. This duo ultimately helps minimize shedding, reduce breakage, and promote hydration to your hair and scalp.

Boldify Hair Thickening Shampoo and Conditioner are infused with an understated fresh scent but still can be tolerated and don’t linger after rinsing. The shampoo may not feel sudsy but the cleansing effectiveness won’t let you down, plus it doesn’t leave a tangled, straw feeling on your hair.
As for the conditioner, it has a little bit thicker texture, a little goes a long way on long hair. Hair Thickening Conditioner is perfect to minimize tangles and make hair more manageable afterward.

Hair Thickening Fibers
For: Anyone looking for an instant solution to cover thinning and bald spots. Suitable for all hair types, best suited for fine and thinning hair.
Uses: Instantly camouflage thinning hair, bald spots, and patches on your crown, temples, and sides with a realistic “real hair” effect finish.

Hair Thickening Shampoo or Serum can take months to deliver visibly thicker, fuller hair. However, there’s a solution to style your hair as usual as you wait for the products to work i.e. Boldify Hair Thickening Fibers.
Crafted with all-natural ingredients, Boldify uses cotton instead of wool keratin which makes this hair fiber allergen- and irritant-free. Boldify offers follicle-like shape fibers to effortlessly cover thinning and bald spots, making your hair appear fuller.

Boldify Hair Thickening Fibers provides long-lasting coverage that resists water, sweat, and wind until you wash your hair. Boldify is clump-free, which makes it easy to apply without involving hassle steps.
Since it has a powdery texture, the application may get easily messy if someone isn’t careful. Moreover, Boldify is more suitable for people in the early stage of thinning hair or baldness. It may be not effective to cover large thinning areas or huge bald spots.

- strengthening serum,

Just a dime-size amount of this thickening serum, will repair your damaged hair and enhance strand strength, which ultimately reduces breakage and excess shedding.
It has a pleasant scent, not overpowering, which is a plus point for people who are sensitive to fragrance. Since it is a finishing – not a treatment – serum, we suggest not placing this serum on the scalp or at the top of your hair to avoid an unnaturally shiny or greasy appearance.

To gain the benefits, this drug-free treatment serum is applied directly to your scalp once a day, preferably before bedtime.

Boldify Hair Boost Serum contains a natural DHT-blocking ingredient, namely, saw palmetto, which makes this suitable for people looking for DHT-level-reducing treatment. If you want to know more about hair serums in detail, check out our 18 best hair serum article for every hair type and problem.

This hairline powder delivers a natural-looking coverage finish, especially on your hairline. Boldify Hairline Powder stays in place for up to 48 hours or at least until you wash your hair.

While you can use an applicator to apply hair fibers to your hairline, sometimes it may look kinda fake and splotchy. With Boldify Hairline Powder, you’ll get a natural-looking, enhanced hairline or beard without clogging pores.

Let’s see how Boldify works as a thickening solution for your thin, fine hair.
How Boldify Works – Active Ingredients Breakdown
From Hair Thickening Spray to Hairline Powder, Boldify is formulated with tons of ingredients that may confuse you. In this section, we give you a simpler explanation of their benefits and how they work to be able to deliver thicker- and healthier-looking hair.
Epsom Salt: Popular Regimen for Hair Volumizer
The famous Boldify’s Hair Thickening Spray is equipped with Epsom Salt which is rich in magnesium and sulfur, which is also known as Magnesium Sulfate. This inorganic salt is beneficial to enhance hair buoyancy and volume by removing excess oils from your hair.
People with oily hair or scalp may see the best results if using Epsom salt-containing products, and so do folks with dry, curly, and damaged hair.
Biotin, The Most Buzzed-About Ingredients
Besides being abundant in eggs, fish, spinach, and broccoli, Biotin is arguably found in almost all hair supplements. Despite getting oral Biotin, it is also a staple in topical hair products, in this case, Boldify Hair Thickening Shampoo & Conditioner, Hair Thickening Serum, and Hair Boost Serum.
Biotin (also called Vitamin B7) plays an important role in supporting the production of keratin (a protein that makes up hair, skin, and nails), which explains how it can improve hair health. This eventually delivers positive implications for promoting thicker and longer hair, strengthening hair strands, and improving overall hair health.
How Saw Palmetto Benefits Hair
The most well-known benefit of saw palmetto is reducing and preventing hair loss. If you are in a strive to reduce DHT levels, then you are probably familiar with saw palmetto. One study suggests saw palmetto can block the activity of 5-alpha reductase to convert testosterone to dihydrotestosterone (DHT) which can cause hair loss.
Saw palmetto also has anti-inflammatory properties to promote a healthy scalp, which leads to new hair growth.
The Remarkable Benefits of Oils
As we mentioned earlier, almost every Boldify hair thickener contains oils. Lately oiling is an increasingly popular treatment at home to help boost hair growth and provide the next level of hair and scalp moisture. Below are the benefits of oils you found in Boldify hair thickeners:
- Coconut Oil: Prevents hair protein loss when applied before and after shampooing. Packed with omega-3 fatty acids and Vitamin E making it ideal to hydrate dry hair and repair damage.
- Argan Oil: Abundant in antioxidants and fatty acids, argan oil is beneficial to moisturize your hair and protect it from sun and heat tool damage.
- Avocado Oil: Helps seal the hair cuticle cells, which ultimately repairs, moisturizes, and strengthens your hair.
- Peppermint Oil: Stimulates nutrient-rich blood circulation to hair follicles, which then promotes faster growth and reduces shedding.
- Sunflower Oil: Rich in antioxidants, which help to neutralize free radicals. It may also help reduce breakage, leading to hair growth since the ends aren’t splitting.
These are the benefits of each key ingredient of Boldify hair thickeners that work synergistically to achieve thicker and voluminous hair to thin and fine hair.
In the next section, we cover real-life user experiences to discover the effectiveness of Boldify hair thickeners.

Which is Better: Boldify vs Toppik

Frequently Asked Questions
Is hair thickening spray good for hair?
Boldify Hair Thickening Spray is equipped with safe ingredients to deliver a thicker, voluminous look to your hair, especially if you have thin and fine hair. However, the effect is temporary so it will only last until you wash your hair.
Can I use thickening shampoo every day?
It is best to use hair-thickening shampoo every other day or every third day, especially if you have dry hair and scalp. Oily hair is also advisable not to use the shampoo every day, since it will cause dryness which leads to the scalp producing more oil.
