Dr. Berg Nutritionals Scalp & Hair Serum Improved Formula — 2 fl oz, Vitamin D3 & E Lightweight Non-Greasy Botanical Oil for Frizz

Dr. Berg Scalp & Hair Serum is a lightweight, plant-oil blend with vitamins D3 and E formulated to nourish the scalp, reduce frizz, and improve the look of hair strength and shine.

This improved formula combines 13 botanical oils with two essential vitamins to support a healthier-looking scalp and hair appearance for both women and men. The non-greasy liquid absorbs quickly to soften dry, brittle strands, tame flyaways, and add reflective shine without silicones, sulfates, or parabens. Clinically tested and cruelty-free, the serum is presented as an everyday leave-in treatment suitable for a wide range of hair types and styling needs.

How does this serum support a healthier scalp and hair appearance?

The blend of oils and vitamins targets scalp hydration and cuticle smoothing so hair appears less frizzy and more manageable. Vitamin D3 and vitamin E are included to complement the oils' conditioning properties, helping hair look fuller and more resilient.

• 13 plant oils like castor, jojoba, rosemary, avocado for multi-layer nourishment
• Vitamins D3 and E to support overall scalp and hair condition
• Lightweight formulation that absorbs without heavy residue
• Clinically tested and free of sulfates, silicones, and parabens

Can I use this serum on all hair types and how often?

Yes — the formula is designed for straight, wavy, curly, and coily hair as well as color-treated strands. It can be used daily as a leave-in after washing or sparingly between washes to refresh ends and control frizz.

• Apply a few drops to damp hair for even distribution
• Work through mid-lengths and ends; avoid heavy application at roots
• Use nightly for extra hydration or once-twice weekly for maintenance

What key ingredients should I expect and why are they included?

The serum relies on a concentrated mix of plant-derived oils plus vitamins chosen for their conditioning and smoothing characteristics. Each ingredient contributes a specific texture or protective benefit to help hair look smoother and less prone to breakage when styled.

• Castor oil for thicker-feeling, conditioned strands
• Rosemary oil to help maintain a refreshed scalp environment
• Jojoba and avocado oils for lightweight moisture and shine
• Vitamins D3 and E to support the scalp and protect hair from environmental stress

How does this serum fit into a daily styling routine?

The serum doubles as a conditioning leave-in and a styling primer that smooths hair before heat styling or air-drying. A small amount reduces frizz and adds gloss without weighing hair down, making it a convenient step for busy mornings or evening hair care rituals.

• Use before blow-drying or straightening to reduce frizz and add protection
• Apply after styling to finish and boost shine
• Mix a drop with a daily cream or styling product for added slip and shine
