"I was always insecure about my hair because of how dry and brittle my ends were until I tried this product. This is so easy to stick with and it lasts me so long I barely even think about it. I just use it whenever I wash my hair and now it's the longest and healthiest it's ever been! 10/10."

    Why Your Hair Isn't Growing

    Every month, your hair grows about half an inch — but if your ends are splitting and snapping off, that new growth disappears before you ever see it.

    Sable's split end serum seals those fragile ends so your hair can finally keep the length you earn.

    We Do It Differently

    How It Works

    This lightweight, leave-in treatment repairs and smooths damaged ends from the inside out.

    Nourishing lipids and strengthening peptides bond to weak strands, sealing frayed edges and restoring silky softness without weighing hair down.

    With consistent use, it helps prevent new breakage and keeps hair looking smoother, stronger, and visibly longer.

    FAQs

    Can I use it on dry hair?

    Yes Mend & Renew works beautifully on both damp and dry hair. Apply it after styling for a sleek, polished finish or on towel-dried hair to lock in moisture and prevent frizz.

    How much product should I use per application?

    A pea-sized amount is usually enough for mid-length hair. Adjust based on thickness or length - a little goes a long way.

    Where should I focus when applying it?

    Concentrate on the mid-lengths to ends - that’s where damage and frizz start. Avoid the roots to keep your hair looking naturally light and bouncy.

    Can I use it with other styling products?

    Yes, Mend & Renew layers easily with heat protectants, leave-ins, and oils. Apply Sleira first to seal ends and smooth the cuticle, then finish with your usual styling routine.

    Is the serum silicone free?

    Yes, it’s crafted without heavy silicones that can cause buildup. The smooth finish comes from nutrient-rich botanical oils and bond-repair actives instead.

    Can I use it with wigs or extensions?

    Yes. Mend & Renew is lightweight and residue-free, making it safe for extensions, wigs, and treated hair — it keeps everything looking smooth and natural.
