Shoppers praise hair serum that ‘adds volume’ for ‘fuller’ appearance

Mature shoppers are praising a targeted hair serum that they say helps ‘add volume’ and creates a fuller-looking finish, making it a popular choice for those noticing thinning or flat hair. Now, the Exclusive Nioxin Pro Clinical Age Defense Leave-In Scalp Serum (70ml) is up for grabs for £57.50 from LookFantastic and shoppers are rating it highly.

Designed to support both scalp health and the appearance of thicker strands, the treatment is gaining attention for delivering visible results without the need for complicated routines. This serum is said to be formulated to nourish the scalp while helping hair look fuller from the root.

Used as a leave-in treatment, it is designed to fit easily into daily routines without needing to be rinsed out. Key ingredients include castor oil, which helps lock in moisture, and niacinamide (vitamin B3), known for its nourishing and hydrating properties.

Together, they are said to support a healthier scalp environment, which is an important factor in achieving stronger, more voluminous-looking hair. The formula also contains caffeine, which helps invigorate the scalp and may assist in reducing the appearance of excess hair fall, while lauric acid brings antibacterial properties to help keep the scalp feeling fresh.

Lightweight and easy to apply, the serum works without weighing hair down, making it suitable for those wanting added volume without losing movement. Finished with a soft sandalwood-inspired fragrance, it adds a subtle, luxurious touch to routines while helping hair appear thicker, healthier and more revitalised over time.

An alternative is the Philip Kingsley Overnight Scalp Barrier Serum with Triple Balancing Action (60ml) for £32 from M&S. This one is said to help strengthen the natural skin barrier function and then overall improve scalp health.

Boots also has The Ordinary Multi-Peptide Serum for Hair Density and Scalp Support – 60ml for £21.90. This one targets the look of thinning hair with a multi-active complex and works to promote scalp health.

However, the Exclusive Nioxin Pro Clinical Age Defense Leave-In Scalp Serum (70ml) has been rated highly on LookFantastic, as one person said: “It has a lightweight formula, and it lathers well without being too harsh and rinses out easily without leaving residue buildup. My scalp feels healthier, and I’ve seen less breakage when brushing and styling. It adds volume, which is great for finer or ageing hair.”

Another added: “This serum is so good. It has attractive packaging and is easy to use with the dropper. I have been using it for a while; it’s lightweight, absorbs well, and doesn’t leave any sticky residue. I have noticed my hair looks healthier, fuller, and smoother than before.”

A third person wrote as part of a longer review: “This serum makes my scalp feel so much healthier. I’ve been using it daily for a month now and will definitely be repurchasing to use long term.”

A handful of others disagreed slightly, as one said: “Really good shampoo! Although I originally thought it was sulphate free, after doing my research I realised it wasn’t, so I have only used it a few times as I didn’t want to ruin my hair extensions, really good product though and durable.”

Another added: “It gives a deep clean and leaves my scalp feeling fresh, almost tingly, which I actually like. After using it, my hair felt a bit stronger and looked fuller, but it’s not a dramatic change.”
