Hydrolyzed Keratin 500 mg: Strong & Shiny Hair, Resistant Nails, Elastic Skin – Advanced Structural Nutrition with KeraGLO® for Regeneration & Visible Shine

Hydrolyzed Keratin 500 mg from Doctor's Best delivers KeraGLO® hydrolyzed keratin (500 mg per serving) in reduced molecular weight form, designed for superior absorption and utilization by body. Keratin is key structural protein present in hair, nails and skin's outer layer, rich in sulfur-containing amino acids (especially L-cysteine) forming disulfide bridges – elastic "clips" that confer fiber strength, flexibility and shine. Formula is completed by modest sodium intake (15 mg, 1% RDI) and has as objective restoring beauty's structural "scaffolding": volume, density, break resistance and healthy, natural appearance with shine from root to tip.

Detailed Benefits of Hydrolyzed Keratin (KeraGLO®)

• Stronger hair, break-resistant – strength from within

Disulfide bridge between keratin chains is responsible for strand's natural "elastic." Hydrolyzed keratin provides building blocks (cysteine, proline, glycine) supporting these bond restoration, consolidating hair fiber from inside out.

✅ Decreased tendency to break and split ends
✅ "Full" strand with body and density sensation
✅ Easier styling with fewer unruly strands

• Visible shine & cuticle smoothing – polishing effect

Cuticle (strand's outer layer) acts as microscopic scale "coating." When structure is nourished, scales align better, uniformly reflecting light. Hydrolyzed keratin supports this alignment, reducing dull and frizzy appearance.

✅ "Mirror" shine and velvety texture
✅ Frizz control in humid conditions
✅ Groomed appearance between washes

• Recovery after heat styling, coloring & environmental factors

Dryer, flat iron, dye, UV and pollution can "disturb" disulfide bridges, thinning fiber. Internal hydrolyzed keratin supply provides raw material for repair and maintains hair fiber cohesion.

✅ Support for those regularly using heat/coloring
✅ More supple hair with fewer fatigue signs
✅ Increased resilience to daily stress

• Support for healthy hair growth – nutritional foundation

Anagen phase (growth) of hair strand is intensely dependent on protein synthesis. Keratin provides key amino acids for active hair follicle and coherently growing strand with stable diameter.

✅ Growth rate supported by targeted protein intake
✅ More uniform strand along length
✅ Root "fullness" sensation

• Balanced scalp – microclimate for beauty

Comfortable scalp means fertile "soil" for beautiful hair. Through structural role and skin barrier interactions, keratin intake supports local integrity and comfort.

✅ Scalp comfort, reduced sensitivity perception
✅ Friendly foundation for stable hairstyle
✅ Ordered, well-groomed appearance

• Harder, smoother nails – fingertip strength

Nails are keratin quality "showcases." Hydrolyzed keratin intake favors nail plate compaction, reducing chipping and peeling.

✅ Fortified nails with impact resistance
✅ Smoother edges, fewer cracks
✅ Ordered growth, natural glossy appearance

• More elastic skin & supported skin barrier

Skin's stratum corneum contains keratin; this protein's balance influences fineness sensation and comfort. Hydrolyzed keratin as amino acid source supports superficial cellular renewal and maintains lipid-protein "wall" in shape.

✅ More uniform texture, velvety touch
✅ More lasting hydration sensation
✅ Rested appearance, visible tone

• Ally in stress periods, seasonal changes & alert lifestyle

Seasonal changes, fatigue, restrictive diets or intense schedule can affect structural protein synthesis. Targeted keratin source helps "fill nutritional gaps."

✅ Hair and nail beauty continuity in demanding periods
✅ Faster appearance recovery after split ends
✅ Groomed image without disproportionate efforts

• Why Doctor's Best Hydrolyzed Keratin KeraGLO®

• Hydrolyzed for bioavailability – "ready-to-use" fragments
Keratin in intact form has long chains difficult to use. Hydrolysis fragments them into short peptides and amino acids, facilitating absorption and transport to target tissues.

✅ Efficient body utilization
✅ Rapid passage from digestion to structural integration
✅ Consistency in perceived benefits

• Sulfur-rich amino acid profile – elasticity "clips"

Cysteine through disulfide bridges confers fiber strength and memory. KeraGLO® provides relevant amounts of sulfur-containing amino acids, supporting flexible "architecture" of hair and nails.

✅ Elasticity with styling memory
✅ Superior resistance to mechanical demands
✅ Maintaining shape and shine

• Versatility in beauty routines

Whether style involves curling, straightening, coloring or protective hairstyles, internal protein support helps fiber maintain its integrity.
✅ Compatible with various styling habits
✅ Comfort for thin or fragile hair
✅ Easy adjustment in personal care routine

• Who is it suitable for

• People with fragile, dull hair with split ends
- Those frequently using heat or coloring wanting resilience
- Anyone noticing brittle nails with peeling or striations
- People wanting uniform skin appearance and velvety touch
- Dynamic lifestyles with stress and aggressive environmental factors
- Anyone pursuing internal nutritional solution for visible beauty

• How it feels in routine

• Morning – foundation for hairstyle that "holds"

Hair nourished from within gains discipline and hold; styling becomes faster and result – more persistent.
✅ Natural volume, unruly strand control
✅ "Clean" shine, fresh appearance
✅ Less styling time

• Throughout day – resistance & comfort

Well "sealed" fibers lose less moisture and frizz less; nails resist daily impact better.
✅ Stable hairstyle morning to evening
✅ Less vulnerable nail edges
✅ Pleasant skin touch sensation

• Over time – beauty keeping pace with you

As protein intake supports natural restoration, hair and nails regain strength "memory" and skin – fineness and velvetiness.
✅ Density and integrity along entire strand length
✅ Nails with ordered growth, natural shine
✅ Skin with uniform texture and increased comfort

• How it works

• Targeted amino acid reserves for keratinized tissues
Body prioritizes proteins where needed. Hydrolysates provide "ready-to-assemble" pieces for hair, nails and skin where daily wear is maximum.

✅ Rapid structural integration
✅ Coherent hair fiber response
✅ Supported skin barrier

• Natural synergies with collagen, antioxidants & minerals

Keratin works in team with collagen (scalp and dermal support), antioxidants (oxidative stress protection) and minerals like zinc (protein synthesis, skin immunity).

✅ Favorable biological context for beauty
✅ Result stability over time
✅ "Anchoring" in body's general balances
✅ Hair: strength, shine, discipline

✅ Nails: hardness, smoothness, natural shine
✅ Skin: supported barrier, fineness, comfort
✅ Protection: heat styling and environmental factor support
✅ Efficiency: KeraGLO® hydrolyzed keratin for superior absorption and integration
