We tested the Body Builder Shampoo to see if it truly adds volume. Read our honest volumizing shampoo review for thin hair, with tips and product comparisons.
If you have fine or thinning hair, you've probably tried countless volumizing shampoos that promise the world but deliver flat, lifeless strands. The Body Builder Shampoo has been making waves in the beauty community, but does it really live up to the hype? In this review, we'll break down the formula, our testing experience, and whether it's worth adding to your hair care routine.

We purchased the Body Builder Shampoo from C.O. Bigelow – The Oldest Apothecary in America – and put it to the test for two weeks. Our goal was to see if it truly adds body and volume without stripping the hair or leaving residue. Keep reading for our honest verdict, plus tips on how to maximize volume and complementary products from the apothecary.
What Is Body Builder Shampoo?
Body Builder Shampoo is a volumizing formula designed specifically for fine and flat hair. It claims to add thickness and fullness by plumping up each strand, giving the appearance of more voluminous hair. The shampoo is part of a growing trend of 'body building' products that focus on strengthening the hair fiber rather than just coating it with heavy silicones.
We tested the shampoo on a variety of hair types – from straight and fine to wavy and medium-thick. The formula is sulfate-free, which is a plus for those with color-treated hair or sensitive scalps. It lathers well and has a pleasant, subtle scent that doesn't linger too long.
- Sulfate-free and color-safe
- Lightweight formula that doesn't weigh hair down
- Works well for daily use
- Pleasant, subtle fragrance
Our Testing Experience: Does It Deliver Volume?
After two weeks of consistent use, we noticed a definite improvement in volume and body. The shampoo gave our fine hair a noticeable lift at the roots, and the effect lasted throughout the day without needing to refresh. Unlike some volumizing shampoos that leave hair feeling dry or straw-like, this one kept our hair soft and manageable.
We also tested it on a friend with very thin hair, and she reported that her hair looked visibly thicker and fuller after just one wash. The key seems to be the combination of proteins and botanical extracts that strengthen the hair shaft while adding moisture balance. However, if you have extremely coarse or thick hair, you might not see as dramatic a difference, but it still adds a nice bounce.
- Visible lift at the roots
- Lasting volume throughout the day
- Soft and manageable finish
- Works on multiple hair types
How to Maximize Volume with the Right Routine
To get the most out of your volumizing shampoo, pair it with a lightweight conditioner and avoid heavy styling products. After washing, apply a root-lifting spray or mousse to damp hair and blow-dry upside down for extra lift. You can also use a round brush to create tension while drying, which helps lift the roots.

C.O. Bigelow offers a range of products that complement the Body Builder Shampoo. For example, the Full Potential Booster Spray is a great addition to your routine, as it adds instant volume and texture to the roots. Another favorite is the Strong Finish Hairspray, which holds your style in place without stiffness, ensuring your volume lasts all day.
- Pair with lightweight conditioner
- Use root-lifting spray on damp hair
- Blow-dry upside down for extra lift
- Finish with a flexible hairspray
Body Builder Shampoo vs. Other Volumizing Options
We compared the Body Builder Shampoo to two other popular volumizing shampoos we had on hand. The first was a drugstore brand that left our hair feeling squeaky clean but stripped it of moisture, causing frizz. The second was a high-end salon brand that added volume but was too heavy for daily use and left a residue on our scalp.
The Body Builder Shampoo struck the perfect balance – it cleansed effectively, added volume, and kept our hair healthy. It's also reasonably priced compared to salon brands, making it an excellent value for the quality. If you're looking for a reliable volumizing shampoo that doesn't break the bank, this is a strong contender.
- Better than drugstore brands in terms of moisture
- Lighter than high-end salon formulas
- Great value for the price
- Suitable for daily use
Overall, the Body Builder Shampoo is a winner for anyone with fine or thin hair looking to add volume and body. It delivers on its promises without causing dryness or buildup, and it's gentle enough for daily use. If you're ready to boost your hair's fullness, we recommend trying it alongside the Full Potential Booster Spray for an extra lift. Visit C.O. Bigelow today to see the difference for yourself!
