About this product
Looking for a volumizing shampoo and conditioner set that gives fine hair a fuller look? This Hair Biology trio brings together a 12.8 fl oz Volumizing Shampoo, a 12.8 fl oz Volumizing Conditioner and a 6.4 fl oz Thickening Treatment. It is made with biotin, paraben-free and dye-free, and formulated to be safe for colour-treated and aging hair.
Who this volumizing shampoo and conditioner set is built for
Hair Biology writes the Full & Vibrant Collection around thin or fine hair, and describes the shampoo and conditioner as bringing fullness and softness back to fine, thin or flat hair. If your hair is already thick and full, this is not the set the collection was written around. The treatment step speaks to the same shopper: it is made to thicken each strand and fight breakage for a fuller look. The brand also states the formulas are safe for aging hair, which is why the line is framed around hair at any age.
What arrives in the box
This is a full-size set, not a travelling or trial size. The shampoo and the conditioner each hold 12.8 fl oz, so the two wash-and-rinse bottles match, and the thickening treatment holds the smaller 6.4 fl oz. You get three coordinated steps in one box rather than three separate buys. If you were after something for a gym bag or a short trip, the bottles here are larger than that.
Colour-treated hair and the formulae
The set is described as specially formulated to be safe for colour-treated Gray hair, with the formulae protecting colour vibrancy while nourishing strands. That makes it a fit if you colour your hair and still want volume rather than weight. It is also paraben-free and dye-free. The brand does not list other free-from flags for this collection in the product information provided.
Shampoo, conditioner and treatment: how the steps work together
The shampoo is built for weightless cleansing and hydration, while the conditioner uses lightweight nourishment to bring back fullness and softness. Together they aim at hair that reads fine, thin or flat rather than heavy. The Thickening Treatment is the step that separates this set from a plain duo: it is made with caffeine and is designed to help the thickener attach to each strand, for a visibly thicker and fuller appearance. It sprays on at the roots, so it works on the area where fine hair usually shows most. Hair Biology describes the collection as age-inspiring hair care, formulated to work with your hair biology and to be safe for colour-treated Gray hair, so colour vibrancy stays part of the picture.

Where does the thickening treatment go?
Spray it on wet or dry hair, 15 pumps at the roots, covering your scalp from the ear line up.
Do you massage it in?
Yes. Once you have sprayed, gently massage with your fingertips. The brand describes this as the step that finishes the look.
How does the shampoo and conditioner fit around it?
The shampoo and conditioner are the wash-and-rinse pair, and the treatment is the extra step for fullness. The brand does not give directions for the shampoo and conditioner in the product information provided.
If volume is the goal, keep the shampoo, conditioner and treatment together as your usual wash-and-condition routine.
