For thinning hair, the Biolage line to buy is Full Rescue; for fine, flat hair it is Volume Boost. The two lines most guides still recommend, Advanced Full Density and Volumebloom, are no longer sold in the US.
Below is the current Biolage range sorted for fine and thinning hair, with what each product contains, what Biolage's claims actually measured, and the lines that will flatten fine hair.

From the editor
Biolage is the salon brand a lot of clients reach for at the supermarket-adjacent end of the salon shelf. It is good value, and some of it is genuinely good for fine hair.
The catch is that several of its best sellers are moisture lines, and moisture is the opposite of lift. Match the line to your problem before you buy the set.

The short verdict
Thinning or breaking hair: Full Rescue Shampoo with the Invigorating Scalp Serum. Fine, flat hair: Volume Boost Root Lift Spray and the Bodifying Mousse, with Full Rescue or a lighter shampoo to wash.
Skip for fine hair: Hydra Source, its conditioning balm and the Ultra Hydra Source line, which Biolage itself describes for very dry, thick or coarse hair.
What happened to Biolage Advanced Full Density and Volumebloom?
Neither appears on biolage.com or on Ulta's Biolage page in October 2026, and Bond Therapy has gone too. Biolage has not announced a rename.
In practice, Full Rescue now does the thinning-hair job Full Density used to do, and Volume Boost has taken over from Volumebloom. Biolage's own fine-hair article recommends exactly that split.
Biolage Full Rescue: the line for thinning hair
Full Rescue is built on niacinamide and rosemary oil, and Biolage describes it as for "falling, breaking hair". Its headline claim is "+74% resistance to hair fall due to breakage".
Read the footnote before you read the number. It measures breakage from brushing, using the shampoo, conditioner and serum together, against a non-conditioning shampoo. It is about hairs snapping, not hairs falling from the root, and no hair-count study is cited.

Best Biolage shampoo for thinning hair: Biolage Full Rescue Shampoo
A sulfate shampoo with niacinamide and a little rosemary oil, plus conditioning polymers instead of silicones. Biolage says it "camouflages the scalp for reduced visibility", which is the polymers giving each hair a touch more body.
Size: 13.5 oz, $30 at Ulta (4.5 stars from 979 reviews). Honest limitation: ammonium lauryl sulfate is the second ingredient, so it cleans hard; and on its own it is a cosmetic thickener, not a treatment for shedding.

For a thinning part: Biolage Full Rescue Invigorating Scalp Serum
A leave-on scalp serum with caffeine, niacinamide, arginine, rosemary oil and B vitamins. Of the Full Rescue products it is the one that stays on the scalp, so it is the one worth paying for if you only buy two.
Size: 1.7 oz, $36 at Ulta (4.7 stars from 724 reviews). Honest limitation: it is not minoxidil and cites no regrowth data. Alcohol is the second ingredient, which can dry a sensitive scalp.

Full Rescue Conditioner
A cream conditioner Biolage says gives "instant density & supreme strength to weak, fine strands". It contains no dimethicone or amodimethicone, which is good news for fine roots.
Size: 8 oz, $30 at Ulta. Honest limitation: it is a fairly rich base and a small bottle for the price. Keep it from the ears down.

Full Rescue Densifying Leave-In Spray
A thickening spray that Biolage says "instantly thickens the look and feel of hair". The effect comes from PVP, a film-forming resin third in the list, which coats each strand.
Size: 8.4 oz, $36 at Ulta. Honest limitation: the biotin and zinc PCA on the label sit at trace levels after the preservatives. Treat it as a styling spray.

Best Biolage styler for fine hair: Volume Boost Root Lift Spray
A silicone-free root spray of fixative copolymers that Biolage says "expands hair's volume by multiplying interfiber space". Spray at the roots on damp hair, then blow-dry.
Size: 8.5 oz, $29 at Ulta (4.4 stars from 226 reviews). Honest limitation: polymer hold can feel tacky if you overdo it. Two or three sprays per section is enough.

Best Biolage mousse: Biolage Bodifying Mousse
A classic polyquaternium mousse that adds body through the lengths without a stiff finish. It is the best-rated Biolage styler we found, at 4.8 stars from 230 Ulta reviews.
Size: 11.3 oz, $28 at Ulta. Honest limitation: it has a small amount of a dimethicone copolyol near the bottom of the list, so on very oily roots keep it to the mid-lengths.
Biolage Volume Boost shampoo and conditioner: worth it for fine hair?
Only partly. The Volume Boost Shampoo has just been reformulated, and the new version has rice protein, cellulose and peptides on a sulfate base. Its new Ulta listing has only 25 reviews and a 3-star average so far, so wait for the dust to settle.
The Volume Boost Conditioner ($27, 13.5 oz) lists amodimethicone, a silicone, as its third ingredient. Silicone that high can build up on fine hair, so if you use it, keep it to the ends and wash with a clarifying shampoo now and then.

The Biolage lines that weigh fine hair down
Hydra Source (now spelled as two words) is a moisture line with coconut oil and aloe. The shampoo is fine for a dry scalp, but the Conditioning Balm and the Ultra Hydra Source range, which Biolage aims at very dry, thick or coarse hair, are too rich for fine roots.
Strength Recovery is for damaged hair. Its shampoo lists dimethicone sixth, and the conditioner carries shea butter, sunflower and coconut oil, so use them only on the lengths of colour-damaged fine hair.
Is Biolage good for thinning hair?
For hair that looks thin because it breaks, Full Rescue can help it look fuller. For thinning from the root, no shampoo regrows hair, and Biolage itself says you cannot permanently change your hair's genetic thickness.
Wash with Full Rescue Shampoo, massage two or three droppers of the scalp serum into the thinnest areas, and condition only the ends. On damp hair, spray Volume Boost Root Lift at the part and crown.
Biolage Full Rescue Shampoo. It is the current Biolage line for thinning and breaking hair, with niacinamide and rosemary oil. Pair it with the Full Rescue Invigorating Scalp Serum, the only product in the line that stays on the scalp.
For fine, flat hair, Biolage now sells Volume Boost Shampoo, which replaced Volumebloom. It was recently reformulated and has few reviews yet, so many fine-haired readers will do as well with Full Rescue Shampoo plus the Volume Boost Root Lift Spray.
It is no longer listed on biolage.com or on Ulta’s Biolage page in the US as of October 2026. Full Rescue is the current Biolage line for thinning hair.
No. Its claims are about less breakage from brushing and fuller-looking hair, measured with the shampoo, conditioner and serum together against a non-conditioning shampoo. It contains no minoxidil and cites no hair-count study.
Not in the US. Volume Boost is Biolage’s current fine-hair volume line.
The shampoo can suit a dry scalp, but the Conditioning Balm and the Ultra Hydra Source line are moisture-heavy and usually flatten fine hair. Use them only on dry ends, if at all.
The Densifying Leave-In Spray lists biotin and zinc PCA, but at trace levels near the end of the ingredient list. Its thickening effect comes from a film-forming polymer.
