I've not heard of Goldwell before.  I checked their website and they have an excellent section on the structure of hair and split hair.  Unfortunately they don't have the ingredients listed for any of their products. 

If you wanted to tackle typing in the ingredients we could at least look at them and give a try at pointing out any good/bad items.

I would guess that these products would make your hair very smooth and silky feeling.  Both have silicone type products (amodimethicone, cyclopentasiloxane, dimethicone) which some hair types don't do well with unless clarified frequently. Dimethicone - A silicone derivative. Adds luster and sheen

Isopropyl Palmitate - An ester of palmitic acid from coconut oil used to impart silkiness to the skin and hair.

Jojoba Oil - Partially unsaturated Jojoba Oil derived directly from the jojoba bean. Unbleached and chemically unchanged, it is used as a lubricant and sebum emulsifier.

Lecithin - From the Greek meaning "egg yolk". Natural antioxidant, emollient and emulsifier used in a variety of cosmetics.

Panthenol - Member of the Vitamin B complex family used as a hair thickener and conditioning agent.

Stearalkonium Chloride - Cationic surfactant that has excellent substantivity to hair's keratin protein. Reduces static electricity by neutralizing electrical charges on hair. Good conditioning agent.

No, the ingredients are not harsh and you got the results that I would expect.  My only caution would be regarding the -cones.  But if you clarify to remove the -cones before they build up and cause dryness, you should be fine.  (Note:  one sign of -cone build up is the ends of you hair will feel crunchy or stiff).
