Introducing Nioxin, the top choice in professional hair care for achieving thicker and fuller locks. The Nioxin Professionals System 4 Kit specifically caters to those with dry, damaged, color-treated hair exhibiting signs of significant thinning. This intensive treatment for hair and scalp is both clinically and dermatologically proven to enhance hair density and fortify strands while safeguarding color vibrancy. Remarkably, 80% of users experience a noticeable increase in hair fullness after its application. Crafted with a unique combination of vital ingredients including niacinamide, biotin, and caffeine, this formulation nourishes hair roots, activates hair follicles, and strengthens tresses from the root to the tip.

Start your routine by applying the Hair & Scalp Shampoo to damp hair, massaging gently for one minute, then rinse thoroughly. This shampoo is effective in eliminating buildup, such as sebum and pollution, thereby getting the scalp ready for subsequent treatments. Following this, use the Hair & Scalp Conditioner. Apply it generously to both hair and scalp, allowing it to sit for 1 to 3 minutes before rinsing completely. The conditioner restores hydration and offers protection against damage. Lastly, incorporate the Hair & Scalp Thickening Treatment into your regimen. Shake the bottle well, apply to the scalp, and leave it in—do not rinse. This rich treatment is packed with vital nutrients, antioxidants, and plant extracts that nourish and shield both hair and scalp from harm and UV exposure. For optimal results, integrate the Nioxin System 4 Kit into your daily hair care routine. It can also be paired with Nioxin’s styling range, including Hair Gel or Professional Hairspray, making it a great beauty gift option!

This stuff is amazing!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
This stuff is the best I’ve found over all other pastes, powders, and chews. My standard doodle had some nasty plaque buildup on his back molars. I tried everything to clean them up but nothing seemed to work. After reading about this stuff I decided to give it a try. I use it once a day with a finger cot. I’m just about done with the first tube and the results are amazing! The plaque is almost entirely gone and he loves the taste of this stuff. Just ordered my second tube. Very happy!!!!

Already seeing a difference after a few uses!
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
Started using this on our dog after noticing significant build up and have seen an almost immediate difference with semi frequent brushing! Seems pretty effective and is easy to use. Our dog seems to like the scent/flavor as well.

Cat loves it
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
I don't know how well it cleans yet, as we haven't gone back to the vet, but my cat loves the flavor. My cats breath has improved, easy to use because he loves it.

THE CATS APPROVE AND LOVE THE POULTRY FLAVOUR !
Flavor Name: Poultry, Size: 2.5 Ounce (Pack of 1)
We previously had another brand of toothpaste that our cats would not eat voluntarily. They love this one and the poultry flavour. Most of them will voluntarily eat it right from the tube or my finger ( they avoid toothbrushes). So, I have been able to clean their teeth much more frequently.
