Kiehl’s Silk Groom Serum is the perfect finish to a polished look. Its versatility allows women of all hairstyles, from fine and straight to thick and curly, to use it and reap its benefits. This product is made with natural oils, a key ingredient responsible for enhancing moisture and protecting it against harmful factors.

The two primary oils used in the blend include sesame oil and sunflower oil. Sesame oil is derived from sesame seeds and possesses similar moisturizing properties as other nut oils, thus smoothing out and conditioning dry ends. On the other hand, sunflower oil contains high concentrations of ceramides and a beneficial amount of phospholipids. These natural oils act as a protective barrier against the harmful rays of the sun and strengthen your strands.

8. Obliphica Professional Seaberry Fine to Medium Serum

Although best suited for moderate to extreme cases of hair thickness, the Obliphica Professional Seaberry Fine to Medium Serum also works well for fine and thin strands. The primary aim of this hair serum is to strengthen and regenerate damaged hair by creating a protective barrier over the sensitive areas. This includes splits ends, highlighted sections, and frizzy strands.

Its most prominent ingredient, sea buckthorn oil, is a gentle moisturizer which you can safely massage into and easily absorbed by the scalp. The Obliphica Professional Seaberry Fine to Medium Serum should be your go-to for the repair and rejuvenation of dry and damaged hair.

What we really like about it:

  • Quickly tames flyaway and baby hair
  • Promotes intense smoothening of dry and damaged sections

What we’re not huge fans of:

  • The scent is rather unpleasant

9. Moroccanoil Mending Infusion

Ideal for preventing split ends, Moroccanoil Mending Infusion has won quite a few awards, and we completely understand why. This product is a vitamin-fueled hair serum whose three key ingredients each contribute to addressing issues prevalent among women with dry hair. These ingredients include quinoa, argan oil, and baobab extracts.

Quinoa is a protein which helps strengthen weakened patches of hair. Because of its high vitamin E content and level of antioxidants, argan oil helps to nourish signs of damaged hair. Visible signs of damaged hair include frizz, brittle ends, as well as color damage. On the other hand, baobab extract allows for a quicker recovery by increasing hair elasticity and strength. As a result, your hair begins to feel softer.

Although well-known for addressing frayed ends, Moroccanoil Mending Infusion isn’t as suitable for fine hair. This product is best used by those with medium to thick hair. Pro tip: focus on the ends when applying the serum, particularly if you’re working it through your hair while blow-drying.

What we really like about it:

  • Pleasing scent
  • Reduces the appearance of split ends
  • Detangles and makes hair silky and smooth
  • Extremely helpful with unruly hair during humid weather

What we’re not huge fans of:

  • Tendency to result in clumped hair if not applied evenly
  • Leaves the hair stringy and greasy (when used for fine hair)
  • Contains dimethicone (silicon) which might not be as appealing to all users
